A hypnopompic state (or hypnopomp or hypnopompia) is the state of consciousness leading out of sleep, a term coined by the spiritualist Frederick Myers. Its twin is the hypnagogic state at sleep onset; though often conflated, the two states are not identical.

The hypnagogic state is rational waking cognition trying to make sense of non-linear images and associations; the hypnopompic state is emotional and credulous dreaming cognition trying to make sense of real world stolidity. They have a different phenomenological character. Sleepers often wake confused, or speak without making sense, a phenomenon the psychologist Peter McKeller calls "hypnopompic speech."

Hypnogogic imagesEdit

Hypnogogic images are short lived hallucination like images that can occur as some people wake up.

NeurobiologyEdit

Depressed frontal lobe function in the first few minutes after waking – known as "sleep inertia" – causes slowed reaction time and impaired short-term memory.
