What is a hypnopompic episode?

A hypnopompic episode is a type of parasomnia that occurs during the transition from sleep to wakefulness. It often involves vivid hallucinations, confusion, and a sensation of being unable to move, which can be frightening for the individual. These episodes are typically brief and may include auditory, visual, or tactile sensations. They are commonly associated with sleep disorders such as narcolepsy or can occur in individuals without any underlying sleep issues.
