CREPUSCULAR HALLUCINOSIS

   The term crepuscular hallucinosis is indebted to the Latin noun crepusculum, which means dusk or half-light. It is used to denote a hallucinatory state typically arising at dusk, or during any other episode of half-light. The notion of crepuscular hallucinosis should not be confused with the - related - notions of * closed-eye hallucination,*hypnagogic hallucination, and * hypnopompic hallucination.
