The Most Horrifying "Crawling Over a Pile of Your Dead Alternate Selves" Scene Ever Filmed

From io9.com: The Most Horrifying "Crawling Over a Pile of Your Dead Alternate Selves" Scene Ever Filmed:

The clip actually comes from 2009's Triangle, which I'd actually thought was just a standard "trapped on a boat with a killer" movie, with a bit of weirdness here and there. The movie starts out that way, and then turns into a trippy film about a time-loop in which a woman keeps running into her slasher self from another version of the loop. (That's Jess, watching her alternate self kill another alternate self in the clip above.)
