Alright, I just made an account here to ask this question, so hopefully I've come to the right place.

When my sister and I were 9/7 years old respectively we saw a film on TV that terrified us that neither of us have been able to track down in our adult years, but I would love to locate, if nothing else for nostalgic value. My memories of the film are so vague, but I'll try and explain what I remember best I can.

It's a horror movie very much in a similar vein to the Poltergeist movies, with a family being terrorized by ghosts in their home. I'm pretty sure this particular film revolved around shadows, at least most of my memories of it involve shadows. The scene I can remember most clearly involves the oldest daughter in the family lying in bed as the shadows of two large hands slowly come together, casting the entire room into shadow. I seem to remember the film ending with this same girl dying of some mysterious "cancer" related causes. I also seem to remember something about the father hallucinating in the garage, and something about a snake, but that's about as detailed as i can get.

If anyone could point me in the right direction given such little to go on I would be eternally grateful.
