Query: low key haunted house/vampire/late hippie creepfest

This film works well simply because it build an odd isolated rural world where who really knows what is going on. It's creepy because its all played in a SLOW oddball way one little clue or unexplained breeze away from waht. Is the heroine (beautifully played by Zohra Lampert) just still nuts or paranoid. Is it a story about potential infidelity, insecurity and fear in the at the end of the free-love, commune era? Then it could just be a an old farmhouse with a free-spirited and hungry vampire? What? I know. Somehow it works and is a pretty effect little nerve-racker.
