Hehe, that is SOO cute!! Jackson has sleep howled before, no joke!! It was the funniest thing. We were laying in bed and his head just shot up and began howling. I was going "Jackson? Jackson?" but he was still just howling with his eyes closed. I touched him and then he woke up, but it was hysterical! Ya gotta wonder if he heard something or if he was just dreaming.... although I can NEVER get him to howl in real life!!
