The unusual name will certainly get your attention, but fortunately Exploding Head Syndrome is not life-threatening or physically harmful. In a recent study more than 10 percent of people experienced the syndrome, a sleep disorder in which crashing or exploding sounds make it difficult to fall and stay asleep.
Dr. Brian Sharpless, Assistant Professor of Psychology at Washington State University and author of Sleep Paralysis, explains that instead of the auditory neurons in the brain shutting down in the process of going to sleep, they all fire at once causing the loud noises.
