You can't do much about it, nor would I suggest you try. The behavior is not going to be destructive. Should she retreat too much into her fantasy life it could well be a problem, but not desctructive. It would make sense right now to have her evaluated by a mental health clincian for the purpose of investigating the extent to which the fantasy life is a problem and the extent to which it is associated with the experiences in the family.
she does not sleep at all in night. help please
My advice remains the same.
