exploding head syndrome

is a parasomnia – involves undesired events that come along with sleep.
Do you imagine a sudden loud noise or explosion in your head just before falling asleep or just after waking up in the night? Are these sounds normally free of any sense of pain? Do these events wake you suddenly with a sense of fright?
