Incubus syndrome refers to erotic sleep disorders

Incubus syndrome is a neuropsychiatric disorder referring to nocturnal manifestations combining sleep paralysis, erotic arousal, and hallucinations. In 1979, the researcher L. B. Raschka proposed this name to group these episodes with a strong sexual and psychotic dominance. Affected individuals generally retain no memory of them, learning of their actions from their loved ones or their victims.
