If Your Body Suddenly Jerks While Falling Asleep, THIS Is What It Means

The hypnic jerk is most often seen when a person falls asleep rapidly, during, or after they’ve been in an exhaustive state. On rare occasions, when the body is really exhausted the brain will process stages of sleep too quickly, confusing itself into thinking that the body and its major systems are failing.

It responds by jolting you awake with a burst of chemicals, one that the brain might interpret, and then build a dream designed to wake you up, which is the basic premise behind the theory of the ‘hypnic jerk.’
