You look around at the crowds, and no one seems to see you. They walk right by, as if you weren't even there. You look down at yourself, and find that you are wearing a white shirt and pants to match. White slippers are on your feet. You feel that more is different, and so you walk up to a window. In it, you see that your hair has turned white as well, and your skin is remarkably pale compared to what it was in your memory.
Suddenly, you see someone who seems to see you. He looks just like you, except he's dressed all in black, and has black hair. He grins, yet there is no true joy there. He then holds up an item, and you realize. He has your toothbrush. Before you can react, he vanishes into static, which fades to nothing.
Behind you, one of the massive screens crashes to the ground, shattering into as many pieces as there are galaxies. They rain down in every direction, and yet you are unharmed.
