text: The following facts suggest that narcolepsy is primarily a "disease of REM sleep": (1) the similarity between cataplexy and REM sleep atonia, (2) the presence of frequent episodes of hypnagogic hallucinations and of sleep paralysis, and (3) the propensity for narcoleptics to go directly from wakefulness into REM sleep [i.e., SOREMs]. This hypothesis may, however, be too simplistic and does not explain the presence of sleepiness during the day and the short latency to both NREM and REM sleep during nocturnal and nap recordings.
