Movies that still scare us when we're older

Are there any movies that still scare you as you've grown up? I'm almost 40 and
I saw Halloween back in 1978 and it still scares me. But also The Exorcist and
Silence of the Lambs still scare me. In fact, the latter two movies I can't
watch cuz they freak me out. Halloween scares me still but I can watch it over
and over, the sequels as well. I love H2O, too.
