Ask Lemmy

Here's a redditor that describes it quite well:

Me. I have this. Happens several times a night. Sounds like a door slamming or a gunshot. The weirdest part is you also get the feeling that there was an impact, like that feeling when someone stomps near you. So it’s not just auditory it’s almost physical. It’s a very strange thing and hard to describe because you’re always 3/4 of the way asleep when it happens. I’ve had it my whole life and always found it curious but have never questioned it out loud. I thought everyone had this until I saw “exploding head syndrome” on the internet. Asked my parents and siblings, no, none of them have this and what the fuck am I talking about? I’m in my goddamned 40s and thought this was normal.
