(ANSWERED)
I get its to prevent dust etc from getting in, but when sleeping your body is usually relaxed and not tense, but dead people aka people who can litteraly not be tense dont have their eyes closed but slightly open, why do we sleep with our eyelids closed if they stay open when theyre not moved by muscles, doesnt our body then have to like constantly put a bit of restraint on the eyelids to keep them closed? or has it just become so natural that it barely matters

Not a scientific answer, but the idea that your body has to tense certain things even whilst sleeping isn’t completely foreign to you, after all, your body has to maintain breathing and bladder control whilst sleeping (at least for most people). Breathing in particular involves muscle usage. Your heart still has to beat. You can still maintain many functions and yet be at rest, it doesn’t mean all motion and work has stopped for your body.
Edit: what I should have said in conclusion is, though somethings require effort for your body when it wants to mostly rest, somethings have such a big pay off it’s worth operating whilst at rest. Keeping the eyes protected from dirt and dust when you are unconscious and can’t avoid it with manoeuvring is of high enough value to expend effort keeping the muscles tense when sleeping.
