Dangerous spiders you've seen, heard of etc.?

[Kriven]

That's a pholcid (at least it looks like it from the body shape. Since I'm not really an expert I guess I shouldn't just blatently state facts), and are actually harmless except, like you said, being creepy. A colony of them always turns up behind my dresser, which my bed is pressed up against, so I constantly worry about them crawling onto me while I'm sleeping (although in my brain that gets translated to their spindly legs reaching out and wrapping around my face to haul me into the darkness where I'll slowly be eaten over a number of days...)

They actually eat other spiders though, so I guess they're not a bad thing to have around if you don't like the kind that can actually bite you.
