A 2021 study published in Current Biology titled "Real-time dialogue
between experimenters and dreamers during REM sleep has discovered that
individuals who are asleep and experiencing a lucid dream, which is a
dream where the individual knows that they are in the midst of a dream,
can "perceive questions from an experimenter and provide answers using
electrophysiological signals." These answers are provided while they are
dreaming.
The study points out:
“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.
Lucid dreamers were
able to follow instructions to compute mathematical operations, answer
yes-or-no questions, or discriminate stimuli in the visual, tactile, and
auditory modalities. They were able to respond using volitional control
of gaze direction or of different facial muscles. There were three
different participant categories.”
Pretty remarkable isn't it?
The fact that lucid dreamers were able to communicate with the
researchers, who weren't dreaming, is quite mind altering...<<<Read More>>>...
