Lips of Blood (1975)

Pierre is haunted by a persistent dream in which he spends the night with a beautiful women in a white gown who lives in an ancient mansion, though she invariably awakes with no memory of him. He is convinced that his dream has some basis in his past, but his mother scoffs at the notion. One day, he sees a photograph in a perfume advertisement that looks just like the mansion he's seen in his dreams, and arranges to meet the woman who took the pictures at a movie theater. While he waits for her, he encounters the mysterious woman in white, and as he follows her, he discovers a strange coven of the living dead -- a band of beautiful women who need to drink human blood to survive.
