Visual snow?

To see it, I have to be in a very dark place for like 20 or 30 minutes.

It's very dim and not super obvious but it's there and it usually moves in waves across my vision.

Sometimes it starts in the center of my vision and moves out in a ring wave, sometimes it starts in a blob and moves around the center of my vision.

It only happens when my eyes are totally adapted to the dark so I always thought it was the visual pigments firing off randomly

I really only see it when I'm having trouble sleeping. I will try to focus on it and it often puts me to sleep.
