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.
Huh?? Do I see differently than everyone else? I can definitely still see my one closed eye's darkness. It's like a 98% transparent overlay on my open eye's vision that's a slightly different colour.
Good analogy, but not for me, one eye is very dominant, so if I cloae that lid initially I see out of the other eye but slowly it all fades to black as my dominant eye tries to take over and feed the blackness to my brain. Then it sonetimes reverses to vision again.
