Me: Did you have any dreams last night?
Me: What did you dream about?
Rooby: I dreamed about everything.
Me: Did you dream about…hippos?
Me: Did you dream about…giraffes?
Rooby: No. I dreamed about polar bears.
Me: Oh! What did you dream about them?
Rooby: I was very big, and I went stomping along with them.
