Hypnopompia

Sleep and Consciousness Phenomena

Hypnopompia, also called the hypnopompic state, is the state of consciousness a person passes through on the way out of sleep, a term coined by the psychical researcher Frederic Myers. Its mirror image is the hypnagogic state that occurs at the onset of sleep, and although the two are often conflated in everyday use, they are not identical and have a different phenomenological character. Hallucinations occurring in either state are frequently accompanied by sleep paralysis, a state in which a person is consciously aware of their surroundings but is unable to move or speak.
