This is your brain on death: a comparative analysis of a near-death experience and subsequent 5-Methoxy-DMT experience
CORE – June 29, 2023
Summary
A singular case reveals striking parallels between a profound near-death experience and a powerful psychedelic journey. Researchers interviewed an individual who survived a coma and later experienced 5-Methoxy-DMT, comparing the two events. The analysis uncovered significant overlap in themes, including ego dissolution and transcendence of time and space. Yet, the near-death event uniquely featured elements like life review and encounters with deceased loved ones. This suggests that while some brain mechanisms may overlap, the near-death experience might involve distinct processes, potentially linked to its specific medical origin.
Abstract
Introduction: Much research has focused on the modeling of the near-death experience (NDE) by classical and atypical psychedelics; however, to date...

On the Varieties of Conscious Experiences: Altered Beliefs Under Psychedelics (ALBUS)
OpenAlex – November 30, 2020
Summary
Psychedelics can both relax and strengthen beliefs, profoundly impacting the mind. Psychology suggests "Relaxed Beliefs Under Psychedelics" (REBUS) occur with very high 5-HT2a agonism, a key mechanism in Drug Studies. Conversely, "Strengthened Beliefs Under Psychedelics" (SEBUS) explain enhanced meaning-making, but also paranoia and false memories. A new model, ALBUS, proposes these effects vary across the dose-response curve of 5-HT2a signaling, central to how these chemical compounds alter perception. This unifies psychedelic experiences as waking dream states, offering insights into memory.
Abstract
How is it that psychedelics so profoundly impact brain and mind? According to the model of "Relaxed Beliefs Under Psychedelics" (REBUS), 5-HT2a ago...

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
Summary
During lucid dreams, people become aware they're dreaming while remaining in REM sleep - a fascinating intersection of consciousness and unconsciousness. Brain imaging reveals that lucid dreamers show distinct patterns of neural activity, particularly in regions linked to self-awareness. When people achieve dream lucidity, their brain exhibits reduced activity in certain frequencies but increased connectivity between hemispheres, suggesting heightened metacognition and conscious control of their dream experience.
Abstract
Lucid dreaming (LD) is a state of conscious awareness of the ongoing oneiric state, predominantly linked to REM sleep. Progress in understanding it...
Tinnitus, lucid dreaming and awakening. An online survey and theoretical implications
arXiv Preprint Archive – April 02, 2025
Summary
People with tinnitus experience relief from their phantom sounds while dreaming - over 90% report complete silence during sleep. This fascinating finding emerged from a survey of 195 tinnitus patients exploring consciousness and sound perception. Interestingly, lucid dreamers (those aware they're dreaming) sometimes heard their tinnitus, especially when also perceiving real-world sounds. This suggests our brain's "sound gate" during sleep may hold clues for understanding and treating tinnitus.
Abstract
(1) Background: Tinnitus is the perception of phantom sound in the absence of a corresponding external source. Previous studies reported that the p...
Towards a Passive BCI to Induce Lucid Dream
arXiv Preprint Archive – April 29, 2019
Summary
Scientists discovered that external light signals can be seamlessly woven into our dreams, opening new paths to achieve lucid dreaming - the rare ability to consciously control our dreams. Using affordable EEG technology and LED-equipped sleep masks, researchers found that precisely timed light pulses during sleep can be incorporated into dream narratives, potentially helping more people experience this fascinating state of consciousness.

Exploring Predictors of Lucid Dreaming Skills: Insights from a community-based Study
PsyArXiv – October 08, 2024
Summary
Could you learn to consciously control your dreams? Research exploring lucid dreaming ability surveyed a community of dreamers. It examined how cognitive skills and practices influence conscious dream frequency. Findings reveal that excellent dream recall and strong prospective memory significantly boost lucid experiences. Consistent reality testing also proved highly effective. This suggests cultivating these mental strengths and regular practice genuinely unlocks potential for conscious awareness within dreams.

To be or not to be hallucinating: Implications of hypnagogic/hypnopompic experiences and lucid dreaming for brain disorders.
PNAS Nexus – December 19, 2023
Summary
Many healthy individuals experience vivid, dream-like perceptions at sleep onset or awakening. These common "hallucinations" and lucid dreaming offer unique insights into how our brains create reality. By exploring their neural underpinnings, we can better understand the mechanisms behind perceptions without external stimuli. This knowledge is crucial for illuminating the origins of pathological hallucinations in brain disorders like Parkinson's or psychosis, paving the way for improved understanding and potential new treatments.

We are the Sensors of Consciousness! A Review and Analysis on How Awakenings During Sleep Influence Dream Recall.
Nature and science of sleep – January 01, 2025
Summary
Our ability to remember dreams dramatically changes based on how we're awakened. Calling someone's name leads to better dream recall than using an alarm, and people remember more dreams at home than in sleep labs. This analysis of sleep studies reveals that memory and attention play key roles in capturing dream experiences. Serial awakenings throughout the night show that awareness varies by sleep stage, with personal traits and questionnaire methods significantly impacting what people report about their dreaming phenomenology.
Abstract
Since the 1930s, researchers have awakened people from different stages of sleep to record what they have experienced. While some aspects, includin...

The Phenomenology of Offline Perception: Multisensory Profiles of Voluntary Mental Imagery and Dream Imagery.
Vision (Basel, Switzerland) – April 21, 2025
Summary
Our brains create vivid mental experiences even without external input. Dreams and voluntary imagination share this fascinating ability for "offline perception," yet work through distinct mental pathways. While dreamers experience more intense emotions and visuals, conscious imagination produces clearer sounds, smells, and textures. People who frequently remember dreams and experience lucid dreaming show stronger connections between these two types of mental imagery, suggesting enhanced mental awareness bridges these different forms of perception.
Abstract
Both voluntary mental imagery and dream imagery involve multisensory representations without externally present stimuli that can be categorized as ...

The Experience Elicited by Hallucinogens Presents the Highest Similarity to Dreaming within a Large Database of Psychoactive Substance Reports
Frontiers in Neuroscience – January 22, 2018
Summary
Lysergic acid diethylamide (LSD) elicits experiences most similar to high-lucidity dreams, a significant finding in Psychology. A semantic similarity (geometry) analysis of a large volume of subjective reports confirmed this hallucinogen, a potent psychoactive substance, mirrors dream states more closely than other drugs. This work in Psychedelics and Drug Studies explores altered states of consciousness, showing hallucinogens have the highest dream-like similarity. Understanding these effects, potentially linked to Neurotransmitter Receptor Influence on Behavior, could inform future Biochemical Analysis and Sensing Techniques.
