Sleep is a form of thinking. We basically "see a movie" when we dream. The entities we perceive interacting with each other in the dream, what are they? Like say there is a person I am am talking to in my dream. Or a crocodile? Or a car I drive in my dream. What are they?
I can think of no other answer than that they are "thoughts". They are thoughts I think in my dream. But they are visual, not verbal thoughts. And verbal thoughts? They are typically "audible" thoughts, I hear them in my head.
It's been reported that what people seldom dream about is reading some text, which is curious. Maybe there's no need for that because brain can dream words directly, as spoken words you hear in your head.
