Lucid Dreaming is the ability to become aware and to recognize that you are dreaming, while you are still dreaming. The instant you realize that you are in fact dreaming, the experience will transform into a vivid and tangible event. Also you will acquire the ability to control every aspect of this dream. Just by wishing, you can make anything happen. Everything is possible!
With this ability you will have the opportunity to dream of anyone whom you desire and it will be as if you are actually with them. You can hug and kiss them or do what ever your heart desires. The experience is so realistic and memorable. Can this be the miracle that you are searching for?
There is a state of consciousness in which any human being could experience anything imaginable. Each of us holds within us infinite possibilities. How many of us ever have the opportunity to taste even a hint of them? If we speak of our fantasies of wider vistas of life, we talk of our "dreams." In our dreams, we are free. A man in a dungeon can dream he is a king in a castle, and while he dreams, it is so.
People have long viewed dreams as blessings or curses beyond our control. However, according to Tibetan Buddhists, who for a thousand years have been practicing a form of dream yoga, similar to what in the west is called lucid dreaming, it is possible to gain complete mastery over dreaming. Recent scientific research at Stanford University has begun to provide objective evidence for that claim.
As is well known to NightLight readers, lucid dreaming means dreaming while knowing that you are dreaming. Everyone has, in theory, the capacity to learn to dream lucidly, because everyone dreams every night. Whenever we dream, we find ourselves in complete worlds, as richly detailed, moving and impressive as the world of waking life. This ability to create worlds is the natural endowment of the human mind. In dreams, this wondrous talent is fully demonstrated. The worlds we create in our minds are so convincingly real we cannot easily tell them from the "real" world of waking.
Lucid dreamers develop a frame of mind that allows them to recognize when they are dreaming. From that point, they are free to do as they choose. This freedom, hard to imagine in our highly constrained waking reality, is astonishing, exhilarating, and inspiring. The laws of physics and society are repealed. The limits are only those of the dreamer's imagination.
Who would not want such a genie at their command? Today, lucid dreaming is a reality, currently being enjoyed and explored by thousands of people. However, for it to achieve its potential of expanding the horizons of all humanity, research advances are necessary. Current training in lucid dreaming takes more time and effort than most people are able to commit. Technology exists to assist people in attaining the state, but although it can greatly enhance a person's chances of having a lucid dream, cannot yet guarantee it.
Research into the factors of brain and mind that underlie the lucid dream state could lead to breakthroughs allowing an individual to lucid dream at will, thereby having reliable access to any imaginable experience. This is much more than a remote possibility. Much is already known about REM sleep, the sleep state in which lucid dreaming occurs, and progress has been made in determining how brain activity changes when a person becomes lucid in a dream. Resources are needed for initiating intensive research into the precise nature of the lucid dream state, and the factors of brain, body and mind involved in achieving and sustaining it.
A convenient and reliable means of entering lucid dreams will open the door to a vast treasury of valuable applications. In worlds of unlimited possibility, creativity will become the rule, rather than the exception. People will be able to sample any way of being they wish, living out fantasies unavailable in waking life, or rehearsing for successful futures.
Experimentation in lucid dreaming is completely risk-free, so ideas in business, politics, ecology, athletics, or indeed, any endeavor can be tested in the model world of dreams. Practice in lucid dreams can improve performance, and prevent costly errors in waking reality. The potentials of mental imagery and hypnosis will also be accessible to everyone, because dreams are the most vivid of all images, available even to those who do not have the ability to create vivid mental imagery or to enter deep hypnotic states while they are awake. This brings with it the possibility of enhanced healing capacities, hinted at in research on mental imagery. People may be able to use lucid dreaming to shorten the time it takes them to recover from illnesses or operations, and to stimulate the redevelopment of physical skills following injury.
All that is required to bring these possibilities to fruition is the devotion of research effort into the area of lucid dreaming. The more resources are supplied to this work, the more rapidly progress will occur, and the sooner this priceless tool will be available to help humanity overcome its present crises. It is abundantly clear that we are in need of quickly developing our capacities for understanding our role on Earth and creatively evolving to survive and grow into our true potential. Lucid dreaming offers great promise for helping us to achieve these goals.
With my colleagues (notably, Lynne Levitan and William Dement), I have been researching lucid dreaming at Stanford University for over a decade. I founded the Lucidity Institute to advance research on lucid dreaming and potentials of human consciousness, and to apply the results of this research to the enhancement of human health and well-being.
The Lucidity Institute has advanced towards the goal of making lucid dreaming universally accessible by developing commercially available lucid dream induction devices such as the DreamLight and DreamLink that help people have lucid dreams.
We are continuing research at Stanford aimed at enhancing the ability to have lucid dreams, and tapping the great potentials within them. Those wishing to contribute to the advancement of research on lucid dreaming please consider the following:
* A tax deductible donation to Stanford University, directed specifically "for research on lucid dreaming under Dr. Stephen LaBerge."
* A loan or investment in the Lucidity Institute, Inc. (Currently the Lucidity Institute Private Placement Memorandum is offering $600,000 worth of stock. Approximately $200,000 has been sold already, leaving $400,000 available.) The Lucidity Institute will provide long-term research funding.
The general aim of our ongoing program of research is the investigation of consciousness and mind-body relationships during sleep. Our primary focus has been lucid dreaming , a state of consciousness with remarkable potential. During lucid dreams, people can reason and remember clearly, and act volitionally upon reflection, while remaining sound asleep and continuing to dream vividly (1).
Lucid dreaming makes possible a new paradigm for dream research. Because lucid dreamers can carry out specific dream experiments, control their dreams and communicate with the laboratory while still asleep (2), scientists can now study the dream state directly. We have pioneered the laboratory study of lucid dreaming (1,2,3) at the Stanford University Sleep Research Center, and thus are well positioned to employ lucid dreaming in the study of the nature of human consciousness and to explore the applications of lucid dreaming in health improvement.
Although we have shown that lucid dreaming is a learnable skill (8), currently available methods, involving mental concentration, require considerable investment of time and effort. Therefore, we have sought methods for helping dreamers to realize that they are dreaming by means of external cues applied during REM sleep that become incorporated into dreams and remind dreamers that they are dreaming. We have tested a variety of stimuli, including tape recordings of the phrase "This is a dream" (9), conditioned tactile stimuli (10), and light (11). Light appears to be an excellent stimulus. We have developed computerized lucid dreaming induction devices (the DreamLight, DreamLink, and most recently, the NovaDreamer) that have produced highly promising results. By further developing and perfecting these and new devices and techniques, we hope to make lucid dreaming widely available.
Lucidity cue type and mental preparation: Preliminary studies on the DreamLight device have been promising: 55% of 44 subjects had at least one lucid dream during one study (11). Unpublished research indicates that combinations of the light cue with mental exercises specifically designed to increase one's awareness of the nature of dreaming tend to be more effective than using the cue alone. At this point we do not know what rate of flashing will be most effective. Therefore we plan to compare four different flash rates (1, 2, 4, and 8 flashes per sec) and three different kinds of mental preparation (MILD, discrimination training to recognize the light stimulus, and post-hypnotic suggestion) in a group of 40 subjects. We also are planning testing cues in other sensory modalities such as sound and vibration.
Physiological correlates of dream content and incorporation of stimuli: Four channels of EEG and four channels of autonomic physiology is being collected from each of 12 to 24 subjects as they are stimulated with flashes of light during REM sleep. Reports of incorporation of light as well as other dream content will then be correlated with the EEG and other physiological measures. Sometimes the subjects will see the light flash in their dreams, but sometimes they will not. Using a computer, we will analyze the EEG and autonomic physiology immediately prior to the time that the stimulus is triggered, looking for differences between the cases when the light is incorporated, and when it is not. By showing us which are the optimal times for applying cues to the dreamer, this research should teach us how to more effectively induce lucid dreams with light.
Our work with lucid dreams so far has led to new insights into the connection between mind and body. In a series of studies (summarized below) we have discovered that various dreamed experiences (including time estimation, breathing, singing, counting, and sexual activity) produce effects on the dreamer's brain (and to a lesser extent, body) remarkably similar to the physiological effects that are produced by actual experiences of the corresponding events while awake.
Correspondence between dreamed and actual eye movements We have found that there is a very high degree of correlation between the direction of gaze shift reported in lucid dreams and polygraphically recorded eye movements, a fact that we make routine use of by using eye movements as signals in all of our experiments (1,2).
Communication from lucid dreams We are also planning to improve the capacity of lucid dreamers to communicate with the waking world while dreaming. At this point, they do so by means of eye-movement signals, which are difficult to execute with any complexity. In past studies we have done some preliminary work with a glove containing computerized movement sensors allowing the recording of hand movements during dreaming. The devices were too crude at that point to permit us to see the fine detail needed for distinguishing various hand signals. Current devices are much more sophisticated. We hope to make it possible for lucid dreamers to communicate by means of hand gestures (e.g., American Sign Language) so that we can have on-the-scene reports from the dream world. A glove with movement sensors will be used to study communication from lucid dreams by means of hand gestures, using five expert subjects.
Dream time How long do dreams last? We have been able to receive a direct answer to this age-old question by asking lucid dreamers to estimate various intervals of time while dreaming. The dreamers marked the beginning and end of estimated dream time intervals with eye movement signals, allowing comparison of subjective "dream time" with objective time. In each case, the intervals of time estimated during the lucid dreams were very close in length to the actual elapsed time (1), as shown in the figure below.
Time estimates during waking and REM lucid dreaming. [EEG: electroencephalogram, ROC, LOC electro-oculogram from right and left eye; EMG chin electromyogram.] While awake (top panel), the subject signaled with eye movements, estimated 10 s by counting, signaled again, estimated 10 s without counting, and signaled a third time. The lower panel shows the subject carrying out the same task in lucid REM sleep. The time estimates are very similar in both states.
Control of respiration during lucid dreaming We recorded the physiology of three lucid dreamers who had been asked to either breathe rapidly or to hold their breath in their lucid dreams, marking the interval of altered respiration with eye movement signals. They reported successfully carrying out the agreed-upon tasks a total of nine times. In each case, a judge was able to correctly predict from the physiological records which of the two breathing patterns had been executed (4). We are currently collecting more data to further determine the precise nature of the dream respiration connection.
Brain function lateralization during lucid dreams Alpha activity was derived from right and left temporal EEG while four subjects sang and counted in their lucid dreams. The results indicated task dependent lateralization: the right hemisphere was more activated than the left during singing; during counting the reverse was true. These shifts were similar to those during waking singing and counting (5).
Physiological responses to sex in lucid dreams A pilot study with two lucid dreamers (one male and one female) who reported experiencing sexual arousal and orgasm in lucid dreams revealed patterns of physiological activity during dream sex closely resembling those accompanying corresponding experiences in the waking state (6).
These studies indicate that the effects of dream events on the brain and body are much more like the effects of real events than like those produced by waking imagery (1). Because dream activities produce real physiological effects, lucid dreaming may be useful for facilitating health and healing, as an extremely potent form of mental imagery. We plan to continue our explorations of awareness in dreams along these lines with the goal of producing a detailed map of mind-body interactions during dreaming sleep for all measurable physiological systems. Such a map could prove to be of inestimable value for experimental dream psychology, as well as for psychosomatic medicine.
EEG mapping of lucid dreaming In past studies, we have determined that lucid dreams are generally initiated during periods of high autonomic nervous system activity--decreased finger pulse amplitude, increased respiration rate and irregularity, and increased eye-movement activity relative to normal REM sleep (12). These factors indicated that dream lucidity occurs during periods of relatively high brain activation, suggesting that sufficient activation of the CNS is necessary before consciousness can be attained. However, we had little idea what was specifically happening in the brain, whether the activation was general, or localized in some particular areas.
In a pilot study we mapped the distribution of brainwave activity from twenty-eight electrode placements on the scalp, examining different frequency bands of EEG during periods pre and post-onset of lucidity in five lucid dreams from one subject. The most interesting findings in this preliminary analysis were in the alpha band (8-12 Hz), where decreases of alpha activity were seen in the posterior left hemisphere, in the first 30 seconds of lucidity. This finding is in keeping with an earlier analysis we performed on a few of our lucid dreams at Stanford of left/right ratios of alpha activity, finding the only difference at lucidity onset to be a decrease of alpha activity in the left parietal region. Decreased alpha activity is generally considered an indication of increased brain activation. Indeed, lucid dreaming ought to be associated with left hemisphere activation, (where language is localized), since to become lucid one must actually spell out to oneself, "This is a dream."
We plan to add to and check our findings by collecting more data from more subjects. This will give us a larger sample of non-lucid REM for comparison and show what EEG differences are consistent for all lucid dreams. Thus, we will gain a basis for the comparison of lucid dreaming with other states of consciousness. Twenty-eight channels of EEG will be collected, and maps of EEG activity will be computed, allowing the determination of which brain regions are involved in lucid dreaming (and perhaps reflective consciousness in general). Five expert lucid dreamers will be studied.
In addition to being a powerful research tool in scientific explorations of the dream state, lucid dreaming also offers considerable potential for a variety of practical applications, which include aiding personal- development, enhancing self-confidence, overcoming nightmares, improving mental (and perhaps, physical) health, facilitating creative problem solving, and more (1,7). There is a great deal of public interest in this area; we have received well over 10,000 letters from people around the world wishing to know more about lucid dreaming. For this reason, and because we believe lucid dreaming can benefit humanity, we feel that we have a service to perform in making the lucid dream state more readily accessible.
We would like to explore several potential applications of lucid dreaming. One is the use of lucid dreaming in overcoming nightmares. We have anecdotal evidence suggesting that lucid dreaming should be extremely beneficial to nightmare sufferers, giving them the means to overcome their own fears (1). Not only will they be able to alleviate their nightmare problems, but in so doing they will be able to increase their self-confidence and self-esteem. Lucid dreaming can be a very empowering experience, which is one of the reasons we would like to make it more readily available to people. An experimental self-help group for nightmare sufferers will be started and the efficacy of lucid dreaming to overcome nightmares will be studied and documented.
Lucid dreaming could provide the handicapped and other disadvantaged people with the nearest thing to fulfilling their impossible dreams: paralytics could walk again in their dreams, to say nothing of dancing and flying, and even experience emotionally satisfying erotic fantasies. Such sensorimotor practice could conceivably facilitate recovery from stroke.
Finally, lucid dreaming can function as a "world simulator." Just as a flight simulator allows people to learn to fly in a safe environment, lucid dreaming could allow people to learn to live in any imaginable world; to experience and better choose among various possible futures.
Our goals are to further explore mind-body relationships and the expansion of consciousness during sleep through lucid dreaming. Specifically, we plan:
A. To make lucid dreaming more accessible by further investigations with biofeedback devices like the DreamLight
B. To study physiological correlates of dream content and of the incorporation of stimuli into dreams
C. To map the EEG correlates associated with the emergence of consciousness during lucid dreaming
D. To explore applications of lucid dreaming

Morning naps provide us highly favorable circumstances for inducing lucid dreams. Two important factors are at work here: timing and wakefulness during sleep. (The term "nap" indicates that the target sleep period is immediately preceded by a period of wakefulness; "morning" indicates the relevant time-of-day.) A series of NightLight experiments exploring the relationships between napping, length of sleep, continuity of sleep, biological rhythms, and lucid dreaming, have repeatedly demonstrated a strong relationship between taking morning naps and increased likelihood of lucid dreaming. (1, 2, 3, 4)
Working from the premise that lucid dreaming is associated with increased REM propensity and REM intensity, both of which are typically at or near their peak late in the morning, the first of our nap studies, "The Best Time for Lucid Dreaming," (1) compared the following sleep schedules: a. Taking a two-hour nap two hours after getting up two hours early (i.e., taking a nap at the normal waking time) and b. Taking a two-hour nap starting four hours after getting up two hours early (i.e., taking a nap two hours later than the typical rising time) to assess their relative value in promoting lucid dreams. Overall, lucid dreams were 10 times more likely in the naps than the preceding nights. More lucid dreams per total dreams occurred in the two-hour delayed nap than in the four-hour delayed nap (an average of one lucid dream out of each two dreams versus one lucid dream out of each three dreams, respectively). Although the number of subjects in this study was not large enough for the differences between the two napping conditions to be statistically significant, it was very encouraging that these nap schedules showed much more effect on lucid dreaming than any of our previous studies of lucid dream induction by mental exercises.
Our second nap study, "Get Up Early, Take a Nap, Be Lucid," (2) compared three different sleep schedules, one each night. In the first schedule, Condition A, participants awakened 90 minutes before their normal waking time, stayed up for 90 minutes, and did a special MILD exercise for 10 minutes before falling back to sleep for a 90-minute nap. In the second sleep schedule, Condition B, participants also awakened 90 minutes prior to their normal waking time, but then went right back to sleep after doing the MILD exercise for 10 minutes to finish a "normal" night's rest. In the third sleep schedule, Condition C, subjects slept their complete normal sleep time, woke up and did the MILD exercise, then returned to sleep for 90 extra minutes. In Condition A (delayed nap), 8% of participants had lucid dreams in the night, and 67% in the nap; none of the participants had lucid dreams in the night portion of Condition B ("normal" sleep with MILD), and 33% in the nap; 17% of participants had lucid dreams in the night portion of Condition C (prolonged sleep), and 8% in the nap. In other words, Condition A (which included the delayed nap) was, by far, the sleep schedule most conducive to lucid dreaming, with a full two-thirds of participants recording lucid dreams under these circumstances. The results of this study indicated that there was something about the delayed sleep that greatly improved lucid dreaming ability, as the prolonged sleep in Condition C, which happened in the same time of the morning as the Condition A nap, was not associated with these elevated levels of lucidity.
The value of a period of wakefulness in promoting lucid dreaming has been known since the late 70s when LaBerge noted that certain activities "in the middle of the night" have been observed to increase the likelihood of lucid dreaming upon a subsequent return to sleep (3). Patricia Garfield, (4) for example, found that, in her case, "sexual intercourse during the middle of the night was often followed by a lucid dream." Scott Sparrow, in contrast, found that early morning meditation favored lucid dreaming (5). Additional anecdotes cited by LaBerge (3) indicated that early morning reading or writing was also favorable. The diversity of these activities suggested that it is not the particular activity, but the alert wakefulness that facilitates lucid dreaming during subsequent sleep. (3)
Following up on this observation, in our third experiment, "The Best Time for Lucid Dreaming: Naps, Mishaps, and Recaps," (6) we planned to study the effect of varying periods of wakefulness before naps (10 minutes versus 90 minutes), but due to an ambiguity in the instructions, many participants did not start their naps at the same time for the two conditions, confounding the impact of varying periods of a.m. wakefulness with changes in the circadian phase. Also, those who were asleep less time probably had less time in REM and, thus, less opportunity for lucid dreams. Despite these complications, we were able to effectively compare the first and second parts of sleep, which again showed a.m. naps to be much better than nights for lucid dreaming.
The fourth in our series of nap studies, reported in NightLight 4.4 (7), compared lucid dreaming frequencies in morning and afternoon naps. The results were clearly in favor of morning naps. Nine of the eleven participants had more lucid dreams in morning naps. Two had the same number of lucid dreams in each napping condition. None had more lucid dreams in the afternoon than the morning. Time asleep, for both nap conditions, was approximately one hour. There were slightly fewer total dreams recalled from afternoon naps, but the difference was not of statistical significance. Hence, it seems that the different times of day must somehow be responsible for the varying levels of lucidity.
In sum, past nap experiments demonstrate the great impact of morning naps in achieving lucid dreams, but leave questions such as the optimum amounts of sleep and wakefulness prior to the naps largely unanswered. The current study brings us one step closer to determining the ideal conditions for inducing lucid dreams by clarifying the effects of varying periods of wakefulness (10, 30, and 60 minutes) before morning naps.
Participants in the "Wakefulness During the Night: Aiming Towards the Perfect Lucid Dreaming Technique" experiment (8) followed three different sleep schedules, one on each night. In Condition A, they went to bed 50 minutes past their regular bedtime, awoke 10 minutes before their regular rising time, read about lucid dreaming for 10 minutes, then returned to bed for a nap; once back in bed they set their alarm to awaken them in 90 minutes, then practiced a modified MILD exercise for at least 10 minutes or until they fell asleep. In Condition B, they went to bed 30 minutes past their regular bedtime, awoke 30 minutes before their regular rising time, read about lucid dreaming for 30 minutes, then returned to bed for a nap; once back in bed they set their alarm to awaken them in 90 minutes, then practiced a modified MILD exercise for at least 10 minutes or until they fell asleep. In Condition C, participants went to bed at their regular bedtime, awoke 60 minutes before their regular rising time, read about lucid dreaming for 60 minutes, then returned to bed for a nap; once back in bed they set their alarm to awaken them in 90 minutes, then practiced a modified MILD exercise for at least 10 minutes or until they fell asleep. In other words, the three experimental conditions all allowed for the same lengths of time for sleep and napping and held constant the activity to be performed during the period of wakefulness (reading about lucid dreaming), but varied the amount of morning awake time before the naps. This allowed us to assess what impact varying lengths of wakefulness prior to morning naps might have on lucid dreaming.
Twenty-two people (12 males and 10 females) submitted acceptable data. (9) Ninety-five percent of them recalled one or more dreams per night. As a measure of their level of skill in achieving lucid dreams we had asked them how many lucid dreams they had recalled within the last six months, and in their best six months of lucid dreaming. Based on the data provided by the group, we would have expected an average of about one lucid dream approximately every seven nights for each participant if they were not involved in the special conditions of this study. Participants averaged one lucid dream every 36 nights during the nighttime portion of this study, and one lucid dream every 11 nights during the Condition A nap. However, dramatically higher rates were found in nap Conditions B and C. On average, participants experienced lucid dreams once every two nights in nap Condition B, and even more (once every 1.6 nights) in nap Condition C.
Participants reported a grand total of 424 dreams during this study--235 (55%) during nights and 189 (46%) during naps. Three of the 235 nighttime dreams (1.3%) were lucid and 50 of the 189 nap dreams (27%) were lucid. In other words, although 55% of the total dreams were reported in the nights, the great majority (94%) of the lucid dreams occurred during naps. Of the 53 lucid dreams, seven were in Condition A (two during nights and five during nap periods following 10 minutes of wakefulness, 20 in Condition B (none during Condition B nights, and 20 in nap periods following 30 minutes of wakefulness), and 26 in Condition C (one in a Condition C night, and by far the highest number of all, 25, during the nap periods following 60 minutes of wakefulness). Nearly half (over 47%) of all lucid dreams from this experiment were reported to have taken place in morning nap periods following 60 minutes of wakefulness. In our current study five times as many participants had lucid dreams in morning naps after 60 minutes of wakefulness compared to naps after only 10 minutes of wakefulness.
Holding the other parameters of this study relatively constant allowed us to assess the impact of varying lengths of wakefulness (10, 30, and 60 minutes) on lucid dreaming in a.m. naps. It appears there is something about the increased lengths of wakefulness that somehow better prepares the brain to become lucid in dreams.
Although five lucid dreams were reported in Condition A naps, 20 during Condition B naps, and 25 during Condition C naps, it is significant to note that of five participants in this study who reported lucid dreams in Condition A naps, four actually took at least 15 minutes beyond the minimum 10 minutes of required MILD time (or a total of at least 25 minutes) to fall asleep. Hence, it may be that if these individuals had fallen asleep after only 10 minutes, they may have had even fewer than five lucid dreams during Condition A naps. Also, this may be yet another indication that longer periods of a.m. wakefulness are much more conducive to lucid dreaming.
Note the preceding statement regarding the relationship between increased wakefulness and increased lucid dreaming may have limits not tested in this study. In other words, we would not want to generalize this statement beyond the current findings for the three periods of wakefulness addressed in this study. It could be, for example, that 120 or 180 minutes of wakefulness may be no more effective, or even less effective, than 60 minutes in bringing about the ideal condition for having lucid dreams. This issue will undoubtedly be of interest in future NightLight nap studies.
Getting up an hour early, staying awake for an hour or more reading about lucid dreaming, doing MILD briefly, then taking a morning nap is an excellent means of achieving lucid dreams. This technique is one of the most powerful, promising means of achieving lucidity.
