- hypnagogic syndrome
- The term hypnagogic syndrome is indebted to the Greek words hupnos (sleep) and agein (to lead, to transport). It was introduced in or shortly before 1987 by the Cypriot philosopher and psychologist Andreas Mavromatis to denote the basic characteristics of the hypnagogic and hypnopompic states (i.e. the transitional states between wake-fulness and sleep during which " hypnagogic and " hypnopompic hallucinations can occur). Mavro-matis distinguishes seven features characteristic of the hypnagogic syndrome, comprising psy-chophysical relaxation, shift to 'passive volition', shift to parasympathetic predominance, reduction of exteroceptive and proprioceptive input, psychological withdrawal, decreased arousal, and need or intention to sleep and/or "dream.ReferencesMavromatis, A.
