“…Previous research indicates that 88% of all people experience one of these phenomena at least once in their life (Raduga, Kuyava, & Sevcenko, 2020). In this study, we use the general term phase state (PS) or phase (Raduga, 2004) to refer to all states with the two characteristics of REM sleep and consciousness. Using this umbrella term allows us to observe a more complete physiological picture than would be possible while considering any single phenomenon in isolation.…”

Objective. Lucid dreams (LDs) are dreams in which people are aware of the unreality of the events taking place and can influence the plot. People can experience lucid dreaming either intentionally or unintentionally and can experience different emotions and perceptions that can lead to psychophysiological consequences upon waking. In this study, we investigated the possibility of achieving hypothermia during LDs and its traces after waking.Method. Through an online experiment, we instructed 92 volunteers to achieve hypothermia while in an LD and then check whether the effect achieved in an LD remained after awakening. If the hypothermia remained, participants reported how long it lasted.Results. Of the volunteers, 88% experienced hypothermia while dreaming – of these participants, 36% were able to transfer hypothermia into wakefulness, though for only a short period.Discussion. We suggest that transferring hypothermia from an LD to wakefulness is mostly possible due to hypnopompic hallucination. The outcomes of our research contribute to the psychophysiological correlations between LDs and wakefulness, their theoretical applications in health treatment, and the nature of lucid dreaming and hypnopompic hallucinations.

“…Several other phenomena share LD' primary features (e.g., consciousness during REM sleep), including sleep paralysis 50,51 , false awakenings 52 , and out-of-body experiences [53][54][55] . These states are grouped under the term phase state (PS) 55,56 or dissociated REM state 57 . A survey revealed that 88% of people have experienced at least one phase state; 43% of people experience one or more of them often 58 .…”

Objective Many people have dreams nightly and some maintain consciousness during dreams. Such dreams are referred to as lucid dreams (LD). During dreams, our speech correlates with facial muscle activity, which is hard to decode, but LD could solve this problem. The primary hypothesis of this study was that the facial muscles electric activity during LD corresponds to specific sounds. Understanding this connection could help decode dream speech in the future. Material and Methods Under laboratory conditions, four LD practitioners were asked to say “ I love you ”, a phrase with a distinctive electromyographic (EMG) signature. They did this before falling asleep and then again after becoming conscious during a dream. Their facial and neck EMG was recorded in four areas. Results All four volunteers accomplished the goal at least once. The patterns associated with the “ I love you ” phrase were observed in most cases, both during wakefulness and LD. Specifically, the “ I ” triggered distinctive phasic activity in the submentalis area most of the time, while “ you ” did the same in the orbicularis oris . Discussion This study highlights the possibility of detecting only specific and highly EMG distinctive phrases from dreams because vocalization also involves a tong and vocal apparatus. The most interesting consequence of the present results is that they indicate the possibility of creating an artificial EMG language that could be instantly decoded in reality and used during LD.

“…The effectiveness of an LD induction technique can vary depending on which method is used. For example, performing techniques while falling asleep in the evening has the lowest efficiency (Raduga, 2004(Raduga, , 2014.…”

Lucid dreams (LDs) are characterized by the presence of consciousness and the ability of a person to influence the dream plot. At present, LD induction is a challenging task, and a comparative analysis of LD techniques is needed. In this study, we compare the effectiveness of different LD induction techniques, including phantom wiggling, observing images, and imagining movements. All the techniques are intended to transfer consciousness from wakefulness into a dream. In an online experiment, volunteers were instructed to try each of the techniques three times following each of the following methods: while falling asleep in the evening (direct method [DM]), while falling asleep after an interrupted sleep (deferred direct method [DDM]), and immediately upon awakening (indirect method [IM]). A report was considered successful if at least one attempt out of three led to an LD. In total, nine attempts were made for each technique. Overall, 1,119 reports were received. For the phantom wiggling technique, the efficiency rates were 11% for the DM, 32% for the DDM, and 24% for the IM. For the observing images technique, the efficiency rates were 11% for the DM, 17% for the DDM, and 31% for the IM. For the imagining movement technique, the efficiency rates were 7% for the DM, 24% for the DDM, and 31% for the IM. Despite the substantial differences among them, all three techniques can be effective for LD induction with similar efficiency. The goal of further studies is to compare all other LD induction techniques to find the most and least effective ones. This can improve our understanding of the nature of LDs and the effectiveness of their study.
