Microsleep

Microsleep is a brief, involuntary episode of sleep lasting a fraction of a second to several seconds during wakefulness. It typically occurs when a person is sleep-deprived or experiencing extreme fatigue, causing a sudden drop in attention and responsiveness without the individual’s conscious control.

Scientifically, microsleeps are seen as the brain’s emergency response to overwhelming sleep pressure, momentarily shutting down to restore alertness. This phenomenon often manifests without obvious signs, making it dangerous in activities like driving or operating machinery. Folklore and anecdotal reports link microsleeps to lapses in consciousness sometimes interpreted as supernatural encounters or moments of altered reality.
