it’s not black swan, i know she pulls out feathers. this was a horror/suspense film where they are.. cursed? haunted? i can’t remember. but the clue to know you’re next is a black spot appears on your skin. the woman thought she would be next but could never find her black spot until she looked in the mirror and noticed it along her head/forehead/hairline. when she starts to pick at it, she begins to pull something black out and realizes she next. can’t remember anything else from the movie 🙁
