Indeed. So basically someone made a very high quality video of a creepy dude in a dark room creeping on Facebook and getting really mad. Then (with some special effects they used) they make it look like (almost perfectly) the guy is viewing your profile page, looking through your photos, and creeping on your friends. Then he maps your last known location on Google Maps, looks right at you, and drives over to your house.

It's eerily realistic.
