If you're one of those people that likes to stay up late and scare yourself with stuff on the Internet, here's a wide variety of links in celebration of the approach of Halloween! Note: obviously most of these are linked because of creepiness, not authenticity; I'm not that gullible, not since I bought that fake gypsy curse off the Internet.
✚ This page contains a collection of Youtube ghost videos that the writer swears are scary, and also not those videos were they try to scare you by someone screaming at the end. I have so far been to cowardly to confirm.
✚ This is a really well-done creepy Youtube video. Um. I couldn't sleep after watching it maybe.
✚ Do UFOs freak you out? Then this is the thread for you! (The comments also contain a link to a recording of what happened when one guy apparently decided to fly over Area 51)
✚ Halloween on Cracked!
✚ Um, this is the creepiest thing I ever saw on Australian television.
✚ More good links here at another LJ!
✚ ETA: via bettytron2000, the only manly way to carve a pumpkin
✚ Via David Wong, The 9 Scariest Short Internet Films. I couldn't make it past #3.
Also, If you are looking for a good movie to watch for Halloween this year, I will once again recommend Trick R Treat, because it's a) really good b) very clever, especially if you avoid spoilers and c) actually relates a lot to Halloween, unlike that other famous horror movie set on Halloween. You know, the one about the guy killing all those people on Halloween, on the anniversary of that other killing that also happened on Halloween. I think it was called "The Psycho Killer That Couldn't Slow Down."
Also a safety announcement: here is what to do if you are affected by real-life ghosts or demons!
