the eyes send visual stimuli even when they’re closed, your ears send stimuli all night as well (as do most senses). your alarm wouldn’t wake you if they didn’t. the brain just tunes out minor stimuli

I sleep with my eyes open, well slightly cracked and one of them is half way open. It can be for a few reasons in which mostly all of them have to do with your facial muscles being weak. Sometimes it’s cause by facial nerve issues.

Edit: but I’m assuming that they don’t send visual stimuli to the brain unless you’re in a light sleep phase in which the brain is still slightly active. Like phase 1 when you can be easily woken but don’t remember waking.

It’d depend on the person I’d imagine. Just like how some wake up from hearing in their sleep or like coma patients can hear people whilst unconscious. I’d imagine a person with eyes open could experience something similar.
