Saw Something Strange

Had another vision earlier. I saw into the human world again. There was some guy carving a symbol into a wall. I was just like the one on my mask. Then I got a look at his eyes. They were just like mine except the pupil's were the same size. Then they became normal eyes, and he started mumbling to himself. I didn't here much of it, but I caught the words "Vision" and "Demi-God". Who was that guy? Does he know something about me? And what the bloody hell is this "Vision" that I keep hearing about?
