What do blind people see? (feddit.uk)

Like, is it just total darkness or, the opposite? Is it easier for them to fall asleep given that there's no light to distract them whilst trying to nod off?

I feel like an absolute ass for asking these questions, and I'm honestly not trying to hurt anyone's feelings or anything.

Here's a neat trick to imagine what it could feel like. Close both of your eyes. You see darkness, right? Now close one eye and leave the other one open. You don't really "see" anything out of that closed eye at all. There's no darkness. There's just nothing there.

I saw that some blind people actually have difficulties falling asleep. Because they cant see the sun, their circadian rhythm and they're sleep/wake signals are all out of sync.

For your latter point, does it happen for people born blind or those who have accidents that result in loss of sight?

It appears it can affect both groups, according to this wiki entry:
