If you close your eyes what do you see?

I read once those flashes are caused by cosmic rays darting through the eyes... Don't know if it's true or not

i see shapes and shadows.

When i worked for a brick manufacturing company i swear to god that for the longest time whenever i closed my eyes i just saw walls of bricks and when i dreamt i even dreamed of bricks.

Usually blackness, kind of a red hugh during the day.

Anthracite color

Something like this, but sometimes with a yellowish tinge

Usually an imprint of whatever I was looking at before

When I close my eyes I see very large bosoms

When I close my eyes I see noise.
