Around 1995, I saw a movie in which a woman was experiencing some uncanny visitations. It turned out that the visits were by herself, from some alternate universe or suchlike. She then had to decide whether to sacrifice herself for the other version, os something like that.
I used to think that the movie had Michelle Pfeiffer in the lead role, but by now I guess this was wrong.
