	Hypnic jerk - Wikipedia, the free encyclopedia
		A hypnic or hypnagogic jerk is an involuntary muscle twitch (more generally known as myoclonus or a myoclonic twitch) which often occurs during the transition from wakefulness to sleep (see hypnagogia).
		Hypnic jerks are completely normal, and are experienced by most people, especially when over-tired or sleeping uncomfortably.
		Hypnic jerks are usually felt just once or twice per night.

		A hypnic or hypnagogic jerk is the experience of a large jolt, usually felt just before falling asleep.
		The exact cause of the sudden jerks is not clear, but are two main hypotheses to explain them.
