A new study suggests that a condition known as “Exploding Head Syndrome” may occur in as many as one in five young people.
This condition causes the sufferer to be awakened by a loud exploding noise or noises in their head potentially accompanied by the person even experiencing the sensation of an actual explosion.
This sensation often occurs when a person is just beginning to fall asleep.
