Sleep paralysis involves an inability to move during sleep/wake transitions and often brings negative emotions, while out-of-body experiences—the sensation of perceiving the world from outside the physical body—tend to be more pleasant. An online survey of 329 participants found that positive emotions were more frequent during out-of-body experiences, whereas negative emotions dominated sleep paralysis episodes. People who reported being able to induce out-of-body experiences also experienced more positive emotions during episodes. Auditory, tactile, and visual sensations often preceded sleep paralysis, suggesting an "aura" that could be recognized. Those who had out-of-body experiences without feeling sleep paralysis reported tactile and visual sensations similar to those who felt paralysis, indicating that recognizing this aura might help induce out-of-body experiences in patients to reduce negative symptoms.
Dream reports from out-of-body experiences (OBEs) have a more condensed and interconnected network structure than non-lucid dreams or lucid dreams, suggesting a more coherent and unified narrative. OBEs occur during sleep paralysis, where awareness is maintained while movement is inhibited. The relationship between lucid dreams and OBEs remains debated, with some viewing them as distinct and others as variations of the same phenomenon. This analysis of dream report structure indicates that specific nodes play a more central role in OBE reports, pointing to a specialized network organization.
Sleep paralysis (SP) involves an inability to move during sleep/wake transitions and often causes distress, but out-of-body experiences (OBEs) that occur during SP tend to be pleasant. An online survey of 329 participants divided into groups based on OBE occurrence, OBE induction ability, and SP perception found that positive emotions were more common with OBEs and negative emotions with SP episodes. Participants who reported being able to induce OBEs experienced more positive emotions during episodes. Auditory, tactile, and visual sensations were perceived before SP episodes, suggesting these may serve as an “aura” of SP.
