Real-time dialogue between experimenters and dreamers during REM sleep.
Current biology : CB April 12, 2021 Karen R Konkoly, Kristoffer Appel, Emma Chabani et al. 126 citations
People who are asleep and having a lucid dream—aware that they are dreaming—can perceive questions from an experimenter and answer them in real time using eye movements and facial muscle contractions. In a study of 36 individuals during REM sleep, including frequent lucid dreamers, a novice, and a patient with narcolepsy, participants performed perceptual analysis of new information, held information in working memory, computed simple answers, and gave volitional replies. Correct answers occurred on 29 occasions across 6 individuals, documented by four independent laboratories. This two-way communication channel allows real-time interrogation of dream cognition and characteristics.
Metacognitive Mechanisms Underlying Lucid Dreaming
Journal of Neuroscience January 21, 2015 Elisa Filevich, Martin Dresler, Timothy R. Brick et al. 89 citations
People who frequently have lucid dreams—dreams in which they know they are dreaming—show structural and functional differences in a brain region linked to self-reflection and thought monitoring. The frontopolar cortex (BA9/10) contained more gray matter in high-lucidity dreamers compared with low-lucidity dreamers, and this same area showed stronger activity during a thought-monitoring task in the high-lucidity group. The findings suggest that lucid dreaming and metacognitive abilities share common neural systems, offering insight into how higher-order consciousness can arise during sleep.
Increased Lucid Dreaming Frequency in Narcolepsy
SLEEP April 30, 2015 Michael Rak, P. Beitinger, Axel Steiger et al. 56 citations
People with narcolepsy recall dreams and nightmares significantly more often than healthy controls, and they also experience lucid dreaming—awareness of dreaming during a dream—at a much higher rate. Among 60 narcolepsy patients and 919 controls, narcolepsy patients reported roughly double the frequency of dream recall and nightmares, and their lucid dreaming frequency was about four times higher. Most narcolepsy patients who had experienced lucid dreaming said it helped relieve the distress from nightmares. Medication did not affect lucid dreaming frequency, though it did reduce dream recall and nightmare frequency.
Virtual reality training of lucid dreaming.
Philosophical transactions of the Royal Society of London. Series B, Biological sciences February 1, 2021 Jarrod Gott, Leonore Bovy, Emma Peters et al. 33 citations
Lucid dreaming—being aware that one is dreaming while still asleep—is rare but can be trained by regularly questioning whether current experience is real or a dream. Virtual reality (VR) scenarios containing dream-like elements enhanced this training. Over four weeks, volunteers who received VR-assisted lucid dreaming training showed significantly greater increases in lucid dreaming than those who received no training. Eye-signal-verified lucid dreams during polysomnography supported these behavioral results. Potential mechanisms include synthetic dream-like experiences, incorporation of VR content into dream imagery as memory cues, and dissociative effects of VR that may amplify lucid dreaming training during wakefulness.
Sleep fragmentation and lucid dreaming.
Consciousness and cognition September 1, 2020 Jarrod Gott, Michael Rak, Leonore Bovy et al. 23 citations
Lucid dreaming, where people experience waking-like self-reflection during dreams, is linked to more wake-like brain activity in the prefrontal cortex. This multi-centre study, combining four investigations, examined whether fragmented sleep increases the chance of lucid dreaming. Results showed that self-reported awakenings, polyphasic sleep schedules, and physiologically measured wake-REM sleep transitions were associated with lucid dreaming. However, neither self-assessed sleep quality nor physiologically measured numbers of awakenings showed an association. The findings suggest a nuanced relationship, where certain types of sleep fragmentation, but not all, may relate to lucid dreaming, and the authors discuss possible causal mechanisms.
Acetylcholine and metacognition during sleep.
Consciousness and cognition January 1, 2024 Jarrod A Gott, Sina Stücker, Philipp Kanske et al. 22 citations
Acetylcholine, a neurotransmitter involved in cognition and REM sleep regulation, may play a role in lucid dreaming—a state where metacognitive awareness returns during sleep. Recent studies using acetylcholinesterase inhibitors suggest a link, but the causal mechanisms remain unknown. This review examines theories connecting acetylcholine and metacognition across wakefulness and sleep, analyzing the phenomenon at microscopic, mesoscopic, and macroscopic levels. It develops exploratory hypotheses to guide future research on how acetylcholine receptor activity affects metacognition.
Out-of-body experiences in relation to lucid dreaming and sleep paralysis: A theoretical review and conceptual model.
Neuroscience and biobehavioral reviews August 1, 2024 Teresa Campillo-Ferrer, Adriana Alcaraz-Sánchez, Ema Demšar et al. 14 citations
Out-of-body experiences (OBEs), where a person feels located outside their physical body, often occur spontaneously near or during sleep. This review examines sleep-related OBEs and proposes that maintaining consciousness during the transition from wakefulness to REM sleep (sleep-onset REM periods) may enable them. A new conceptual model is introduced to distinguish sleep-related OBEs from similar states like lucid dreaming and sleep paralysis, and to suggest possible brain activity patterns (polysomnographic features) underlying them. The predictive coding framework is applied to connect sleep-related OBEs with those occurring during wakefulness.
A dream EEG and mentation database.
Nature communications August 13, 2025 William Wong, Rubén Herzog, Kátia Cristine Andrade et al. 10 citations
A new open database, the DREAM database, combines standardized sleep magneto/electroencephalography (M/EEG) recordings with dream reports from 505 participants across 20 datasets, totaling 2,643 awakenings. Each awakening includes at least 20 seconds of high-resolution sleep EEG (≥100 Hz, ≥2 electrodes) and a classification of the sleeper's reported experience. Analyses showed that reports of conscious experiences during sleep can be predicted from objective EEG features in both REM and NREM sleep. The database aims to overcome limitations of small sample sizes and methodological variability in dream research, enabling larger-scale investigations of the neurocognitive basis of dreaming.
The role of mindful acceptance and lucid dreaming in nightmare frequency and distress.
Scientific reports September 21, 2022 Sofia Tzioridou, Martin Dresler, Kristian Sandberg et al. 10 citations
Nightmares are less frequent and less distressing for people who practice mindful acceptance—the ability to experience thoughts and feelings without judgment—rather than merely mindful presence, or paying attention to the present moment. Two studies, one with 338 participants and another with 187 frequent lucid dreamers who used meditation and lucid dream induction techniques, found that acceptance was more strongly linked to fewer nightmares and less nightmare distress than presence. People with high meditation expertise and practice of lucid dreaming techniques reported the lowest nightmare frequency. Among frequent lucid dreamers, more lucid dreaming was associated with higher mindfulness. The findings suggest that the two facets of mindfulness play distinct roles in dream quality, with potential clinical applications.
Electrophysiological Correlates of Lucid Dreaming: Sensor and Source Level Signatures.
The Journal of neuroscience : the official journal of the Society for Neuroscience May 14, 2025 Çağatay Demirel, Jarrod Gott, Kristoffer Appel et al. 8 citations
Lucid dreaming, where a person becomes aware they are dreaming, is linked to REM sleep. To overcome previous research limitations, a new preprocessing pipeline was applied to pooled EEG data from multiple labs. Sensor-level differences between lucid and nonlucid REM sleep were minimal, but source-level analysis revealed reduced beta power (12-30 Hz) in right central and parietal areas, including the temporoparietal junction, during lucid dreaming. Alpha-band (8-12 Hz) connectivity increased compared to nonlucid REM sleep. During eye signaling of lucidity, gamma1 power (30-36 Hz) increased in right temporo-occipital regions, including the precuneus, and interhemispheric gamma1 connectivity rose. These patterns suggest shifts in network communication underlying changes in perception, self-awareness, and cognitive control.
Group-Delivered Mindfulness-Based Cognitive Therapy to Reduce Psychological Distress and Improve Sleep in Patients With Inflammatory Bowel Diseases: A Multicenter Randomized Controlled Trial (MindIBD).
Inflammatory bowel diseases July 14, 2025 Milou M Ter Avest, Marloes J Huijbers, Carmen S Horjus et al. 6 citations
Mindfulness-Based Cognitive Therapy (MBCT) added to usual care reduces psychological distress and improves well-being in patients with inflammatory bowel disease (IBD) who are in remission but experiencing at least mild distress. In a randomized trial with 142 participants, those receiving group MBCT showed a moderate reduction in distress (effect size -0.61) and improved well-being (0.40) after the intervention, with effects strengthening over time. Objective sleep measures indicated less total sleep time but a higher proportion of deep sleep. Although flare rates did not differ, fecal calprotectin levels, a marker of gut inflammation, decreased in the MBCT group over the follow-up period (effect size -0.49). MBCT may benefit both psychological and biological aspects of IBD.
Electrophysiological correlates of lucid dreaming: sensor and source level signatures
bioRxiv Preprint Server April 9, 2024 Çağatay Demirel, Jarrod Gott, Kristoffer Appel et al. 2 citations preprint
Lucid dreaming, a state of conscious awareness during REM sleep, is associated with specific brain activity patterns. Compared to non-lucid REM sleep, EEG sensor-level differences were few. However, source-level analysis revealed increased gamma1 power (30-36 Hz) in left-hemispheric temporal areas during lucid dreaming, potentially reflecting verbal insight processes, and in right temporo-occipital regions including the precuneus around the onset of lucid eye signaling, linked to self-referential thinking. Beta power (12-30 Hz) decreased in right central and parietal areas including the temporo-parietal junction, possibly related to conscious reality assessment. Alpha-band (8-12 Hz) functional connectivity increased, contrasting with psychedelic states and highlighting enhanced self-awareness.
