You absolutely don't have awareness of everything nearby when you're asleep. You are inherently incapable of even determining this because you're sleeping. I'm sure you react to some stimuli but that doesn't mean you can expect yourself to react to every potential stimuli that you would want to.
I would obviously suggest to be very honest with yourself, but if you are a light sleeper and don't roll (we didn't), the most you have to be careful of is heat. Otherwise, enjoy the cuddly night
