About 23% of people with recurrent sleep paralysis report pleasant episodes, though these often include some fear. Pleasant episodes are more likely to involve illusory body movements (vestibular-motor sensations), and some individuals can intentionally induce these hallucinations. The ability to lucid dream and higher openness to new experiences are associated with pleasant episodes. Lower trauma symptoms or higher life satisfaction did not predict pleasant sleep paralysis.
Sleep disturbances such as sleep paralysis, lucid dreams, nightmares, and hypnagogic hallucinations are positively associated with reports of paranormal experiences and beliefs, including those involving ghosts, spirits, and near-death experiences. A scoping review of 44 cross-sectional studies found consistent links between these sleep variables and ostensibly paranormal phenomena. The findings suggest that nighttime experiences many people interpret as supernatural may stem from common sleep disruptions. This has clinical implications, such as reducing misdiagnosis and guiding treatment for sleep-related experiences.
