I saw a movie years ago about a man dealing with two women, a mother and daughter, who were possibly witches and maybe the same person.  It was a black and white movie possibly made in the early 1960s.  I vaguely remember that the man may have been staying at the women’s house.  He eventually realizes there’s something strange about them.  They are deceiving him in some way.  I wish I could remember more, but I think that’s it.  Thanks!
