Im trying to find the name of a film whiched I watched years ago can any help? The film is a 70,s or 80's horror film where this black entity haunts and attacks this family, all I can remember about it is when the couple of the house our in bed it puts the husband in a deep sleep and proceeds to fling the woman about the ceiling.

There was a book called 'the entity' and a film about that time too. Have you checked that one out yet. that is about a woman taken over by something similar to how you described.

Sounds like The Haunted (1991) (TV) (http://www.imdb.com/title/tt0102007/) Here's the scene you described: http://www.youtube.com/watch?v=kmLs15oZWmA&feature=related

That's the scene out of Nighmare on Elmstreet 1 isn't it?

Actually no! no quinn F was right. Scary moment.
