People with narcolepsy, who enter REM sleep abnormally quickly and often experience lucid dreaming, show higher creativity than healthy controls. In a study of 185 narcolepsy patients and 126 controls, those with narcolepsy scored higher on the Test of Creative Profile (58.9 vs. 55.1) and the Creativity Achievement Questionnaire (10.4 vs. 6.4). Objective tests of creative performance in 30 patients and 30 controls also favored the narcolepsy group (4.3 vs. 3.7). Most narcolepsy symptoms—sleepiness, hypnagogic hallucinations, sleep paralysis, lucid dreaming, and REM sleep behavior disorder—were linked to higher creativity scores, suggesting that lifelong heightened REM sleep access may enhance creative potential.

People with type 1 narcolepsy who experience hypnagogic hallucinations (vivid dream-like sensations at sleep onset) show greater creative achievement and potential. In a study of 66 patients, spontaneous mind wandering was linked to creative success, but this link was strengthened by the presence of both sleep paralysis and hypnagogic hallucinations. These hallucinations also shaped patients' creative identity, which in turn predicted higher creative performance on a divergent thinking test (generating original solutions) and real-world creative achievement. The findings suggest that hypnagogic hallucinations trigger mind-wandering processes and influence self-concept, together boosting creativity in narcolepsy.

A small pilot study tested Meditation-Relaxation (MR) therapy for sleep paralysis (SP) in ten patients with narcolepsy. Over eight weeks, the six patients receiving MR therapy showed a 50% reduction in days with SP and a 54% reduction in total SP episodes in the last month, with large within-group effect sizes. The four patients in the control group (deep breathing) did not show similar improvement. These preliminary findings provide the first proof-of-concept evidence that MR therapy may reduce frequent SP, and the authors cautiously suggest the approach might generalize to people with isolated SP.
