microsleep 

NEUROLOGY, SLEEP DISORDERS

A brief episode of sleep of precipitous onset, lasting from a fraction of a second to 30 seconds. It occurs in night-shift fatigue, and is associated with excess daytime sleepiness and automatic behaviour.

Observers are generally unaware of microsleep episodes. During microsleep, the polysomnogram abruptly shifts from waking characteristics to sleep and the individual in the microsleep mode doesn’t perceive external stimuli. 

Aetiology Sleep deprivation, mental fatigue, sleep apnoea, hypoxia, narcolepsy, hypersomnia.
