Need to find movie title?
I watched a movie in elementary school in the early 80's and don't know the name of the movie. A young girl moved into a new house close to a forest. She kept getting called into the forest and was seeing another girls the same age and they looked alike in the mirror or window. (I think the missing girls name was Karen)The girl she was seeing use to live in that house but had disappeared many years before. What happened was a group of teenagers got together in a large circle on the night there was an eclipse and was saying some type of chant and once the eclipse happened the girl disappeared. So at the end of the movie the new girl who moved into the house got this group of people together to do the same thing because there was going to be another eclipse.
