So I posted on here a little while ago and was disappointed with the lack of feedback but now I have a new theory on what's going on in my head. I've been experiencing a zapping like jolt that I hear in my head but only when I lie down and the best explanation I've found for it is Exploding head syndrome. How about that for a name! I don't hear it sitting up or standing. I can hear approximately 5 of them at any one time if I lie down, along with the tinnitus. It's like an electricity shock coursing through your head. Apparently the syndrome is benign, a para insomnia and/or an auditory hallucination and the attacks are known to disappear but most likely will return at some point. There is no pain associated with them, but they are very distressing even though I'm almost getting used to them. I'm hoping these attacks will subside. Has anyone else experienced this?
