I know this is fake. It is pathetically fake. Like a beginner's CGI project. But the creature reminds me of a spider in the way the creature moves. I am no fan of spiders. Of particular spine chill is the way that move, so the way this critter moves is creepy. Ergo, I am sharing the footage as a creepy video.
Comments across the internet frequently claim watching this shadow creature crawling along a Russian building reminds people of Slender Man. I never got into the whole Slender Man phenomenon . The spider similarities are enough for me. Your mileage may vary.
