For me the music cues from the Resident Evil games are the most evocative.
I spent many an hour wandering around those corridors and getting that dread feeling as I opened a door (never has a level loading screen been used to such great effect) so I now have a Pavlovian response when I hear sound files of music.
My ear is also very atuned to the stock sound effects they used and I can spot them in television, radio and film dramas all over the place.
