2 movies which scared the pants off of me years ago.
This one I saw at a slumber party when I was 7 or 8.
And this one I saw when I was pregnant with my firstborn . . . the TV was on when I went to sleep, I woke up near the beginning and began watching it, got creeped out, fell asleep before it was over, and thought it was probably a nightmare. Years later I remembered it and looked it up, and turns out it was a somewhat famous movie by the guy who directed it, about a real location in Australia.
