Looking for ideas for subtle scares

[Putmalk]

Thread title explains it all.

I'm looking for ideas for subtle scares.

I can handle story driven ones (like as you walk through the library, you hear your father threatening to kill your mom in your head), but not like generic ones...I like scripting events, I'm just not the best when it comes to what they actually do.

Hence, any ideas for scares?

In mine there's a library, once you get in the corner you hear a wall thump causing a book to fall down followed by a particle system.

If that's what your looking for.

I like using REALLY quiet noises in my custom story. The kind of ones where you have to stop and listen to hear it properly. Then just as the player starts to get an idea of what the sound is, you stop it. >
