Ansikte mot ansikte (Face to Face) (1976)

Dr. Jenny Isaksson is a psychiatrist whose temporary position at a mental hospital offers only modest responsibilities. With her husband out of the country for a seminar and her daughter at camp, Jenny moves in with her grandparents, expecting a relaxing few months. But it isn't long before unpleasant memories of her childhood, the sudden appearance of strange apparitions, and a near-rape push this otherwise stable woman to the very edge of sanity.
