CORE DEFINITION

Exploding head syndrome involves a sudden perceived loud noise around falling asleep or awakening, sometimes with flashes of light and usually without significant pain. It is not a literal explosion or evidence that cognitive overload has short-circuited the brain. Its precise cause remains uncertain.

SCAFFOLDING EFFECT

Anchor fast decisions

The sound experience occurs around transitions between sleep and wakefulness. Its pathophysiology remains unclear; it does not establish brain injury or a specific stress-induced short circuit.
