Uh you might want to see a doctor because you can't stop breathing when sleeping. It's automatic...
No it's like
my face

What are you even talking about.
I'm not talking about sleep paralysis or controlling your body. Your body is designed to react to stuff regardless of if you're asleep, such as if it's suffocating itself. It will roll over instinctively. Humans are evolutionarily idiot-proofed against themselves.
Well, my body always wakes me up when I accidentally suffocate myself
