When I was a kid, I watched a movie about a family who moved into a new home. Soon afterward, the wife began to be plagued by confrontations of little demons or some type of creature from the underworld. If I remember correctly, they had white, bald heads. They followed her around and tormented her, wanting her to die so she could become their queen. No one else could see them.
I remember a scene where they were at the dinner table and one of the demons was under the table and kept pulling her napkin off of her lap. She kept having to pick it up and no one could understand why she was having such a problem keeping the napkin in place.
Another scene was when she has a priest or preacher over to the house and the demons tripped him and he fell down the stairs and died.
I remember being terrified, but don’t remember much more about the movie.
