Is it normal that when i am tired but trying not to sleep, one eye closes?
This is going to sound strange, but when I was a kid I saw a documentary on Dolphins and thought it was pretty cool how they sleep with one eye open and half their brain is still awake so they can still be alert to danger. I thought it would be really cool if I could do that, it would mean I could stay up all night playing my gameboy or something lol. So anyway, I'd always try shutting only one eye when I was sleepy and eventually it just became a thing I can't help any more. It's not something I really thought about, but my girlfriend noticed me doing it the other day and thought it was pretty funny/weird.
