Okay, here's mine...
Late 70's (possibly 1978), drive-in movie that was the second movie with Halloween (hence the 1978) so it should be a horror film. I was four and supposed to be sleeping in the back of my parents station wagon (they couldn't afford a baby sitter - plus it was the 70's and they were really young). I only saw the first few minutes, then got so scared I ducked under a blanket and fell asleep (I hope). I'm not even sure if this is a real memory (my parents think the movie is real - but don't remember - damn 70's).
Anyway... Here is what I know (I'm pretty sure it's the beginning):
A guy is driving a beat up car down a dirt road. The car breaks down and after trying to fix it, he starts walking and is carrying a crowbar (I think). He gets to an abandoned house, but goes in the door anyway. The house is in good shape (i..e not condemned) but empty. As he look around, he notices there are several mannequins around. He walks upstairs and opens a closet to find another mannequin. He hears a noise, turns around and there is a mannequin standing behind him.
That's where I puss out and duck under the covers. Like I said, I may have made this all up, but my dad sort of remembering this movie makes me think it's real.
Anybody?
