More Sleep Talk

I wouldn't have believed that a two year old would talk this much in his sleep, but I hear him everyday. And it's not unintelligible mumbling, like adults usually do.

Yesterday: "There was one cat outchide; There were two cats outchide; There were three cats outchide; There were four cats outchide;", like he was reciting a book.

Maybe he wakes up a little, talks without opening his eyes, and then falls back asleep.
