Patients with narcolepsy have a high propensity for SOREMPs when they fall asleep during the day. Similarly, nighttime polysomnography in this setting is characterized by short latency to sleep onset, frequent sleep stage transitions and awakenings, and increased likelihood of a SOREMP (REM sleep within 15 min of sleep onset, a highly specific finding for narcolepsy). Patients often experience disrupted nighttime sleep and dream awareness, dream enactment, and other REM sleep dissociative events.

Sleep-related hallucinations are typical in narcolepsy and may be either hypnagogic or hypnopompic. These hallucinations are usually vivid and can be visual, auditory, or tactile in nature.
