Off the bat, I want to say I love your website…I was lucky enough to figure out one traumatic scene from childhood on my own (the head coming out of the table in THE MANITOU), but this one is still nagging at me…
It was the end of a movie I saw when I was about 9 years old…a woman was being chased by a vampire (or Satanist?), who cornered her in an empty in-ground pool. As I remember it, she was saved by the sheriff, but then he locked her in a cell; as it turned out, the whole town were vampires (or something like that), and the movie ended with a freeze frame of her screaming.
It's hard to say why I found it so scary at the time, I think part of it was the low budget film quality-it looked like it was shot on super-8, which gave it a cinÃ©ma vÃ©ritÃ© kind of feeling-but I'd really like to see it again now. Any ideas?
