Structural differences between non-lucid dreams, lucid dreams and out-of-body experience reports assessed by graph analysis.
Scientific reports – November 09, 2023
Summary
OBE dreams demonstrate a more coherent narrative than non-lucid and lucid dreams. An analysis of dream reports revealed that out-of-body experiences (OBEs) exhibited a condensed, interconnected network structure, with specific nodes playing crucial roles. In contrast, non-lucid dreams and lucid dreams showed less structural cohesion. This suggests that OBEs may represent a distinct type of dream experience, characterized by a specialized network that enhances the overall coherence of the dream narrative. Understanding these differences can deepen insights into the complexities of dreaming.

Summary
A woman with severe PTSD experienced a significant reduction in her recurring nightmares after just six weeks of lucid dreaming training. This intervention led to changes in her dream plots and improvements in psychological assessments. Notably, she reported fewer nightmares, highlighting the potential of lucid dreaming as an effective tool for addressing sleep disturbances. Emphasizing the importance of focusing on sleep and nightmares in treating PTSD could enhance public health strategies, particularly when combined with cognitive behavioral therapy for insomnia (CBT-I) and sleep coaching methods.
Abstract
In this case report, we explain the story of a woman diagnosed with severe PTSD, suffering from recurrent nightmares involving a traumatizing event...
Conscious entry into sleep: Yoga Nidra and accessing subtler states of consciousness.
Progress in brain research – January 01, 2023
Summary
Conscious awareness can persist even during deep sleep, suggesting a phenomenon called lucid dreamless sleep. This experience is linked to practices like neurophenomenology and Yoga Nidra, where individuals maintain alertness post-sleep onset. While traditional studies focus on lucid dreaming, which involves awareness during dreams, this lesser-known state has been documented in Indo-Tibetan meditation texts. Exploring these states could deepen our understanding of consciousness; however, substantial empirical validation remains absent. Current methodologies may pave the way for future investigations into this intriguing area.
Abstract
Human sleep is a dynamic and complex process comprising sleep stages with REM and NREM sleep characteristics that come in cycles. During sleep, the...
Out of body experiences: Scoping review.
Explore (New York, N.Y.) – June 04, 2025
Summary
Many report a profound sense of reality during Out of Body Experiences (OBEs). A comprehensive review of 87 publications explored how these unique events occur and their impact. It found OBEs can be spontaneous or induced, often linked to altered states of consciousness like lucid dreaming. While reactions vary, many embrace these as transcendental experiences. This work helps normalize and expand our understanding of Consciousness.
Abstract
Despite the growing body of scientific research on Out of Body Experiences (OBEs), a scoping review has not yet been conducted. A search was conduc...
I did not expect to be dreaming: Explaining realization in lucid dreams with a Bayesian framework.
Consciousness and cognition – August 01, 2021
Summary
A compelling insight reveals that lucid dreams may stem from genuine reasoning rather than mere realization. By analyzing 100 lucid dreamers, a Bayesian model was developed to explain how dreamers assess their situation based on beliefs about what is probable or improbable. This model highlights that the transition to lucidity involves conscious evaluation of one's state, suggesting that understanding dream cognition can enhance our grasp of lucid dreaming. This nuanced approach opens avenues for further exploration into the complexities of dream experiences.
Abstract
The commonsense view is that a lucid dream starts when the dreamer realizes that they are currently dreaming. The notion of realization, however, h...
Patterns of Occurrence of Four States of Consciousness as a Function of Trait Absorption.
Journal for person-oriented research – January 01, 2019
Summary
Individuals with high absorption experience a unique relationship with different states of consciousness. In a study of 251 participants, those scoring just above the median on absorption showed greater differentiation among hypnagogic states, lucid dreaming, and out-of-body experiences. Conversely, those with very high absorption exhibited less differentiation among these states. This suggests that while moderate levels of absorption enhance the ability to distinguish between these experiences, extremely high absorption may blur the lines between them.
Abstract
Four states of consciousness are considered here: the hypnagogic state (the transitional state between waking and sleeping); the hypnopompic state ...
Partial memory reinstatement while (lucid) dreaming to change the dream environment.
Consciousness and cognition – August 01, 2020
Summary
Lucid dreamers showed a remarkable ability to attempt real-time control over their dreams, yet struggled significantly with accurately reinstating waking memories. In a sample of 30 participants, qualitative analysis revealed that 80% of these attempts resulted in inaccuracies when trying to match dream scenes with previously experienced environments. Even when aware of these inaccuracies during the dream, participants could not effectively retrieve or recreate the original context. This highlights a complex relationship between episodic memory and dream control, offering insights into memory retrieval processes during sleep.
Abstract
Lucid dreams often coincide with having control over dream events in real-time, although the limitations of dream control are not completely unders...
