Something not mentioned that I’m curious about, if I’m about to fall asleep and I happen to hear a loud noise nearby, I also see a flash of light with my closed eyelids.

Weird. A spike in blood pressure maybe? Can you do reproduce it consistently on purpose with an alarm or by holding something as you fall asleep that will make a loud noise when it falls?

  Yes, I have never tried to reproduce it on purpose, but it happens consistently enough that I would be surprised if it does not happen at this point. It happens simultaneously with the sound, so I would guess it is purely a weird form of synesthetic hallucination.

Exploding head syndrome?

  The sounds are real, for example someone will ring the doorbell while I’m about to fall asleep, I'll both hear and “see” the sound. I do get explosion head syndrome as well, but that is rare in my case.

You might want to talk to a optician about that. It can be a sign of issues with your retina. I see flashes in a dark room when I wake up, because I have PVDs (posterior vitreous detachment) in both eyes. Edit: I just re-read your post. If they both happen together, I think it is something different.

Could it be that both noise _and_ flash are in your head, and like me you have Exploding Head Syndrome? https://vester.si/bodily-oddities/oddities/exploding-head-syndrome/ https://vester.si/bodily-oddities/oddities/exploding-head-sy...

I've had this many times before too.

  Interesting, so it seems there is at least two of us. I assumed this was more common for some reason.
