“I will concentrate on vengeance, and nothing else!”
You know, I’ve been throwing the word “exorcism” around a lot lately, but I’m not sure that’s the correct term for what’s going on here.
This is the situation: A witch was murdered in 1795, but then her restless spirit moved through time to be reincarnated in 1968. A group of well-meaning occult experts held a séance to call on the ghost of an 18th-century witch hunter who was sealed up behind a wall in their basement, and that ghost tied the dead witch to a tree and said a prayer over her to cast out the demons possessing her, which made her crumble into ashes and disappear.
I don’t think there’s a word for that, because it has never occurred to a single person in the history of the world to even imagine that such a thing could take place. Except for the writers of Dark Shadows, obviously, who can’t think about anything else.
