Why do we talk in our sleep?

Lots of people talk in their sleep, especially kids!  Have you ever heard anyone babbling away in the middle of the night?  Or maybe someone has told you that you do it?  Sleep talking is totally normal, but why do we do it?  We asked sleep specialist Chris Winter to help us find the answer. Got a question that you’ve been dreaming about? Send it to us at BrainsOn.org/contact, and we’ll search through the night for the answer.
