Hello ....I think I can help...This sounds like a night terror. They are common at her age. Have you ever seen one before?
Was she asleep?
I am pretty sure that is all it is. Yes they don't wake up and do not remember it the next day. But they may recur and can go on for about a year. Sometimes they can look quite frightening...like "the exorcist" people say.
