The exploding head syndrome

The exploding head syndrome is a curious phenomenon in which patients describe a frightening loud noise which they experience as they are falling asleep or less frequently the noise awakens them from sleep.  Patients describe the noise as loud violent bang, a bomb explosion, shotgun, thunderclap, enormous roar or crack of lightning and so on.  These phenomena are followed by fear, terror and palpitations or a forceful heartbeat. They may recur several times each night or may be more occasional. Although extremely disturbing to the patient, the exploding head syndrome is usually a benign condition.
