Lucid dreaming is common in young children, with its incidence dropping around age 16. A survey of students aged 6-19 found that those in higher-level schools reported more lucid dreams than those in lower-level schools. The authors propose a link between the natural occurrence of lucid dreaming and brain maturation, considering methodological issues.

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.

Sleep disturbances are common in treatment-resistant depression (TRD). Intravenous (IV) ketamine improved sleep symptoms, which partially mediated its antidepressant and anti-suicidal effects. In 323 adults with TRD receiving four IV ketamine infusions, self-reported improvements in insomnia, night-time restlessness, hypersomnia, early morning waking, and total sleep partially explained reductions in depression severity. Insomnia, night-time restlessness, early morning waking, and total sleep improvements also mediated reductions in suicidal ideation. Each point improvement in total sleep score was associated with 3.29 times higher odds of achieving response or remission (95% confidence interval 2.00–5.41).
