If you boy seems that he is not aware of what he is doing, please DO NOT wake him up. My boy was cry, scream but he couldn't listen to us. He seems awake to me but my doctor told me he really isn't. And it's very harmful to wake hime up at that time since it's just like a nerve break and it should run its course. The best way is to use above method to avoid this thing happen. But if it's happened, don't try to do anything to wake him up or stop him.
