Why You Wake Up Before Hitting the Ground in Dreams?

Why You Wake Up Before Hitting the Ground in Dreams? That sudden jolt you feel in a falling dream is called a hypnic jerk. It happens during the moment your body is drifting into deep sleep. As you fall asleep, your muscles relax and your breathing slows. Sometimes, your brain misinterprets this relaxation as falling. To protect you, the brain sends a sudden signal to your muscles. Your body jerks awake, snapping you out of the dream just before impact. This reflex comes from ancient survival instincts. For early humans sleeping in trees or unsafe places, sudden muscle relaxation could be dangerous. So your brain evolved a quick wake up alarm. That’s why you almost always wake up before hitting the ground your brain won’t let the fall finish.
