I remember seeing a horror flick on TV when I was a kid in the 70s and I want to find out the title. All I remember is a woman being chased by some sort of undead/ghost type characters. I seem to recall the scene being very dreamlike with lots of fog and smoke. She gets to the house of supposedly of someone she trusts, and when that person turns around in their chair they turn out to be one of these undead people. Anyone have an idea of what movie this could be??
