As with most brain questions, nobody knows exactly.
One theory for the purpose of it, is to prevent us from confusing things we dreamed about with things that actually happened.
Edit: Lol, this always gets downvoted, but it’s the truth. We know nothing about the brain; almost all the studies that get reported on are basically this.
