Sleep paralysis and lucid dreaming are both dissociated states linked to REM sleep. A survey of 1928 adults (ages 18–82, 53% female) found that more frequent lucid dreaming is associated with more frequent sleep paralysis, especially episodes involving vestibular-motor hallucinations. Dissociative experiences during wakefulness predicted both phenomena. However, sleep paralysis was predicted by poor sleep quality, anxiety, and life stress, whereas lucid dreaming was predicted by a tendency toward positive, constructive daydreaming and vivid sensory imagery. The findings suggest that dissociative tendencies during wakefulness extend into REM sleep, but sleep paralysis reflects sleep and well-being issues, while lucid dreaming may stem from greater imaginative capacity and positive imagery in waking life.
