The Voice in the Mirror (Nightmare Hall)1995

Salem U. is buzzing with holiday activities. Annie loves the holidays, until two of her friends have horrible accidents—and she may be next. What Annie doesn't know is that one of her friends has a dark past. He has murdered a girl and now his mind is split in two. One part that of a student, the other that of a guilty killer. He listens to "the voice in the mirror" that tells him that each new girl he meets is actually a reincarnation of the girl he killed, returning to expose him. The voice tells him he has no chance, unless he can eliminate the problem...permanently.
