Wow! Now I have a cool name to this phenomenon. Doesn’t happen every night and there are also times I can ignore it because it’s typically not scary, just disruptive. I also see the flashes of light and that can be scary sometimes. I’ll think somebody tried to come in while I’m sleeping or that a nuclear bomb just went off. Or that a cosmic ray hit my eyeball.
Now, is there a phenomenon about seeing random faces in my head while falling asleep as well?
