How Do You Explain a Dream To A 2 Year Old?

Last night around 12:30, Turner started whining and calling for me. I went up and asked him what was wrong. He said that a wasp bit his arm. I asked him which one, and he held up his left arm and said, "This one. And it still hurts." Poor thing. I told him he probably just had a bad dream. He was still whining and said he wanted to rock, but went right back to sleep when we got in the recliner.
