Flashes while drifting to sleep
Not sure if this is a sleep disorder or some other problem, or perhaps it's normal. But sometimes as I'm drifting off to sleep, I'll see a flash of light. It's as if someone is taking a picture with a flash however my eyes are closed.
I thought I've read somewhere that this is similar to your body jerking as you fall asleep, except, it's a visual sleep start.
Has anyone else experienced this?
