What the **** do you want me to do about it?!
Something to try:
Everyone has a Body Elemental being, who is in charge of the non-voluntary functions of the physical body, and sort of looks after it... sees to its growing, repairing, digesting its food, etc., etc. Suggest to your friend to have a conversation with her Body Elemental and ask it to bring her back to her body and wake her up if she is having such a dream and calls (in the dream) for it.
Please let me know if it works... she will, of course, have to believe it will and give it a serious try!
