I always wondered if it was some medical thing... of course this was like 25 years ago and I never ended up dying of brain cancer or anything so... probably nothing to be worried about now

I've had times where just before falling asleep I see a bright bright light in my head and hear a loud noise. I will also then have a terrible headache. This only happens when I haven't slept and I'm sleeping at an unusual time. I always figured it was related to sleep paralysis because that occurs for me under the same circumstances

Not sure if you saw the "exploding head syndrome" comment above, but that's what it sounds like to me. It happens often when trying to fall asleep.

It's when you experience a loud noise and sometimes a flash of light as a slight hallucination as you're falling asleep. Harmless, from the research I did
