It's the dreaded Herobrine from Minecraft. He is a mysterious Minecraft character that has the same skin as Steve, only he has blank eyes. I'm not sure if he's real or not, I haven't seen him. Well, if he is real, Herobrine can be found in Peaceful mode on Tiny Render distance. If you can see two blank dots in the 'fog', it's probably Herobrine (Stalker version). To see the more dangerous version of him (Miner), try to find a cave lit by redstone 2 blocks high, one block in width. But he'll probably kill you.
