This would happen to me when my monitor was right next to my bed. (I believe the flash part, while the exploding/popping sound is external). I would use my computer an hour or more before going to bed, so the monitor would run warm (or even hot). When I'd turn it off and go to bed, the monitor would cool down over the next, I don't know, between 15 minutes to an hour. And at some point during the cool down, the plastic would make a popping sound (just once). This would be around the same time I'd be about to fall asleep. And that's when a flash would go off in my head. This happened pretty much everyday. Now I don't have my monitor sitting next to my bed.
