Has any allegedly real ghost video ever scared you

[fistor!@#]

There's this show called "Ghost Adventures" on the Travel Channel that has some spooky moments. Worth a google search, at least.

I saw some of that this weekend. Those guys were more show than actual "investigation", I thought. Like making sure they're locked in the haunted hotel all night for some reason. What would be the purpose of that? And they were documenting stuff like orbs. :

Some of their stuff was interesting, like the dude getting scratched, but taking the whole production into consideration, it was pretty difficult for me to trust that these guys were on the up and up.

I'm normally pretty cynical when it comes to ghost stuff, that's why it's rare for me to find something that truly freaks me out.
