Sounds like night terrors. My 7 year old use to have them. There was nothing really I could do as with night terrors they are not really awake and can't be comforted. I use to just sit on her bed and rub her back untill the episode was over. She would not remember in the morning. She has not had one in years though. I think they stopped around her 5th birthday. My mom said I use to get them also but I of corse don't remember.
