The books are even better (there are two versions).
Love it.
I know this thread is about movies, but back in 1979 or '80 I was reading "The Shining" during a thunderstorm and got so scared I had to put the book down. The one and only time I ever had that reaction while reading.
"Carrie" was a pretty good scary movie. But you could walk out and laugh when it was over.

As for favorite horror film, it depends. For scariest, it's a tossup between The Exorcist and Alien. If it's just a little scary, Poltergeist is very good. If it's on MST3K, The Brain That Wouldn't Die was Mike Nelson's debut, and that is probably the funniest one they ever did.
Have you ever read Phantoms By Dean Koontz? I had a very similar experience reading it, as did a coworker I lent it to.
