I have a coworker like that. We have flexible hours, so it's not too bad for him, though we do have core hours where we expect people to be available for meetings, etc. Luckily for him, his boss is pretty laid back about such things, and we can also often video conference in from home. So worst-case he gets up for a meeting, calls in, then goes back to sleep. But others like you definitely exist!
