Need Help with Movie Title

I've been trying to remember the name of a movie I watched a few years ago. I would love to rewatch it, but I've forgotten the title. I thought it was The Changeling (1980) now I don't think it is.

It's from the 70's or 80's. Same in tone as The Changeling. The scene I remember most involves a man going to see a psychic. He and some other people hold a seance. I'm pretty sure the psychic is an old woman. Anyway, she starts to levitate out of the room and gets thrown down the stairs.

If anyone knows what movie this is, I would greatly appreciate the help!
