Why do we sometimes talk when we sleep?

The “freeze all motor functions” command in your sleep didn’t work properly, so some motor commands get through from your dream state.
It is usually harmless but it might still suggest some level of sleep disorder.
Everything you do in your dreams, you are trying to do in real life. Pick this up, walk over here, say this.
Your body paralyzes itself while asleep so you don’t do that and potentially put yourself in a dangerous situation. Sometimes, parts of that turns off on accident, so you might say something you are saying in your dream. Other people might sit upright, scream, or move around in bed.
Sometimes your body stays paralyzed even after you wake up, or before you fall asleep. This is sleep paralysis. Since you are still partially asleep, hallucinations are common.
I believe sleep walking is a sort of in-between state. You aren’t 100% asleep and are at least somewhat aware of your surroundings (otherwise you’d walk into a wall), but are still in a dream like state and your body isn’t paralyzed. Sleep walkers are able to see and hear, but aren’t fully conscious, their brains sort everything that happened into the “sleeping” memory file, and therefore forget most of it.
