Did`nt do it for me neither so that`s two of us.

Thanks everyone for the suggestions, I was wondering if there are anymore.

Hi, circa81. I'm a new member, so, of course we're not acquainted. But, we seem to have similar taste in horror movies according to your list. Try these:

Jacob's Ladder (1990)
Suspiria (1977)
Black Christmas (1974)
The Fog (1980)
The Ward (2010)
High Tension (2003)
Dead Waters (1993). Note: Alternate title is Dark Waters.
You're Next (2011). Kind of similar to The Strangers.
