ELI5: Saying random things in your sleep

What is the premise of sleep talking and why do people say completely random things in their sleep? Do names mean anything? And is it possible to say a name you don't have a connection to in some way?

Usually when you're asleep all of your voluntary muscles are turned off, this includes your vocal chords. For some reason, usually due to stress, illness, medications, or mental illness, your vocal chords and the skeletal muscles that help with speech aren't turned off. Usually when people sleep talk it has nothing to do with reality, and isn't always linked to what that person is dreaming about.
