So we're playing hunter tonight

And in grand style this is my second week of creating the story from the ground up. Not all the difficult when you consider I actually have a rather strong cast of players, each with their own histories. Tonight, I'm drawing from M's storyline and bringing in an old Asylum where her character spent some time.

Most of the grounds haven't been used for years, and the parts that are in use aren't all that nice either. We're focusing on mainly the haunted portion for tonights proceedings because of a few things I have to lay out before the game actually begins.

Now, I need a little help. I want to pepper the game with some weird and definitely creepy elements. I have an idea of one of the ghosts "jumping off the top of the building and disappearing before it hits," but the sound continuing, just enough to really freak everyone out. Does anyone have a gif or movie clip from Pulse where that guy falls from the top of the building thingamajig?

Also if anyone has sound clips, door slams, weird laughs, real creepy shit. I'd be most grateful if you could link me or send them my way. ♥ ♥

Any help would be great, the more I can freak out my players the better.
*is an evil storyteller*

Just to give you an idea of what I plan here's something they're going to see on their camera. . .
