I first saw this when I was 9 years old and although it's probably well past dated by now, at the time it was a pretty scary movie for the ABC movie of the week. The tunnel scene with Louis Latham as Nora Piper still gives me chills and the opening sequence with the ESP cards is a pretty good setup to the whole premise of the movie. This was around the time of the TV series "The Sixth Sense" and it has that kind of feel to it. Another ABC Movie of the Week recommendation is "Crowhaven Farm" or even "The Eyes of Charles Sand" which were both creepy and had a sense of dread to them. I kind of wish they made movies like this again or at least try to remake them so they don't seem dated.
