Researchers were able to communicate with people who were in REM sleep and asked them math problems and yes/no questions to prove the person was responding to questions and was communicating.
Researchers asked an 19-year-old American participant to subtract six from eight while he was in a lucid dream, and he correctly signaled the answer “two” with two eye movements from left to right. When asked again, he repeated the correct answer.
The researchers would wake the participant from sleep after achieving successful two-way communication, in order to obtain a dream report.
I, Brian Wang, have personally experienced Lucid dreaming. This is where you recognize that you are dreaming while you are in a dream and then are able to take control of the dream. I was able to do this with about a 30 percent success rate for about one month while in undergraduate university. However, this ended when I had a bad nightmare. I attempted to re-enter and fix the nightmare with lucid dreaming but I was not successful after about eight attempts.
Below are three techniques to train and initiate a Lucid Dream.
Dreams take us to a different reality, a hallucinatory world that feels as real as any waking experience. These often-bizarre episodes are emblematic of human sleep but have yet to be adequately explained. Retrospective dream reports are subject to distortion and forgetting, presenting a fundamental challenge for neuroscientific studies of dreaming. Here we show that individuals who are asleep and in the midst of a lucid dream (aware of the fact that they are currently dreaming) can perceive questions from an experimenter and provide answers using electrophysiological signals. We implemented our procedures for two-way communication during polysomnographically verified rapid-eye-movement (REM) sleep in 36 individuals. Some had minimal prior experience with lucid dreaming, others were frequent lucid dreamers, and one was a patient with narcolepsy who had frequent lucid dreams. During REM sleep, these individuals exhibited various capabilities, including performing veridical perceptual analysis of novel information, maintaining information in working memory, computing simple answers, and expressing volitional replies. Their responses included distinctive eye movements and selective facial muscle contractions, constituting correctly answered questions on 29 occasions across 6 of the individuals tested. These repeated observations of interactive dreaming, documented by four independent laboratory groups, demonstrate that phenomenological and cognitive characteristics of dreaming can be interrogated in real time. This relatively unexplored communication channel can enable a variety of practical applications and a new strategy for the empirical exploration of dreams.
How to Lucid Dream
The first is called “reality testing.” This may involve verifying whether or not you are dreaming both in real life and during a dream.
For instance, throughout the day, a person may want to ask themselves, “Am I dreaming right now?” as they try to make their hand pass through a solid wall.
This technique relies on intention. In real life, the wall will remain solid and impenetrable, but in a dream, the hand will easily pass through it.
Another “reality check” is rereading a line of text. In real life, if we read the text on a poster, it will stay the same when we reread it. In a dream, however, the text will constantly shift.
Conducting these experiments repeatedly throughout the day may make it easier to remember to conduct them during dreams, thus allowing the dreamer to gain awareness of the dream.
Another technique is “waking back to bed.” This requires setting an alarm to wake oneself up around 5–6 hours after going to sleep.
Once awake, the person should aim to remain awake for a while before going back to sleep. This technique is supposed to immerse the sleeper immediately into REM, which is the phase of sleep during which they are most likely to experience a lucid dream.
Lucid dreaming may also occur through “mnemonic induction.” This is another technique that requires intent and lots of practice.
With mnemonic induction, a person must repeat to themselves — just before going to bed — a phrase such as, “Tonight, I will notice that I am dreaming,” so as to “program” themselves to achieve in-dream lucidity.
Dream journals and meditation
It also appears that those who find it easy to lucid dream do not have much trouble recalling their dreams on a regular basis.
“When it comes to lucid dreaming, the strongest predictor of whether you have lucid dreams or not is how good you are at remembering your ordinary dreams,” Dr. Aspy explained.
