I doubt anything's wrong. My daughter goes in and out of stages of this. For a week or two she'll wake up and we'll just hear her talking to herself, singing... then for a period it's like she always wakes up on the wrong side of the bed. At one point I realized that if I went to get her too quickly she'd actually be in a worse mood. It was like she needed time to wake up. Your son probably just doesn't like that groggy feeling. I'm the same way -- and I think if I expressed a bad mood the way a 15 mo does (with tears), I would probably wake up crying every day too! I really wouldn't worry.. but you could try leaving him a few minutes to see if he calms down on his own.
