To anyone who thinks that doppelgangers aren't that freaky, we dare you to look at this photo. There's a reason that The X-Files, Buffy, Orphan Black, and just about every other horror show has dealt with unexplained body doubles - they're scary as heck. We don't know what it is - the thought that you're not as much of an individual that you thought you were, maybe.
Or maybe it's the idea that someone could just take over your life at any time. People have seen their doppelgangers plenty of times over the course of history, and it's not that uncommon. Even we bumped into Channing Tatum the other day. To capture a doppelganger on camera, that you didn't even know existed, is a whole other matter entirely. This coincidence almost seems too good to be true.
