It sounds like "night terrors". It is common and usually they grow out of them or they get less frequent. My daughter used to have them --she is 6 now. She has one once in a while. Itis like they are awake, completely freaked and then goes back
to sleep. They try to shut their eyes,and the terror is still there. Just stay calm . try to rub his back and let it just stop on its own. It is normal -- my doctor said they will grow out of them.
