Usually, when someone has a stomachache or a headache, they don’t feel it when they’re sleeping. When they wake up, they feel it again.
EDIT: Maybe i’m just a heavy sleeper lol

I read in the book ‘Why We Sleep’ that theres a mechanism in your brain which shuts off nerve feedback from your spine. Some people experience sleep paralysis and this is when you have become conscious but for some reason that mechanism still hasnt allowed nerve feedback to travel from spine to brain. So you are awake but you cant move your body.I think it has to do with the thalamus.
“The thalamus acts as a relay for information from the senses to the cerebral cortex (the covering of the brain that interprets and processes information from short- to long-term memory). During most stages of sleep, the thalamus becomes quiet, letting you tune out the external world.”
