Old TV show
When I was younger age 5-8 so 1990-1994 in the era of tv shows like Unsolved mysteries, and the old show Rescue 911 about real 911 stories showing the call and police response. I don't remember what show it was maybe Unsolved Mysteries? But there was a story on the show about a family that had a poltergeist in their house and that it was centered? around the teen daughter? and the camera crew that was filming the story caught the teen (or one of the teens) on the couch and the "ghost" threw a blanket over her head. I grew up in California and had limited TV channels I say this as any cases from the Warrens were not known to me literally until the Conjuring movies started coming out. And I don't believe it was on Beyond Belief because it came out later and remember more of it.
Thanks for the help!
