It begins with a strange door out of place. You don’t even see it at first. It’s just a shadow in the corner of your eye after you’ve passed it. One day after realizing what you see, you stop, but as soon as you do, it’s gone. You shake your head and laugh before continuing with your day. It happens again a few hours later but this time when you stop it’s still there. For a moment, you just stand there in front of the door, but then curiosity overcomes you and you open it only to find your own reflection. “Oh,” you say. ‘How could I not have noticed this before?’ you think to yourself.
