"Exploding head syndrome (EHS) is a condition in which a person experiences unreal noises that are loud and of short duration when falling asleep or waking up. The noise may be frightening, typically occurs only occasionally, and is not a serious health concern. People may also experience a flash of light. Pain is typically absent.

The cause is unknown. Potential explanations include ear problems, temporal lobe seizure, nerve dysfunction, or specific genetic changes. Potential risk factors include psychological stress. It is classified as a sleep disorder or headache disorder. People often go undiagnosed."

I used to have this happen to me when I was 16 and 17.

Occasionally the sound would be only what I can describe as a computer glitch sound. A “electronic” music type sound that was combined with the cliche sound of when a DJ abruptly stops music.

The sounds stopped around 18 years old.
