You are a proxy/ creepypasta in Slendermans mansion.

As you have nothing to do at the moment you explore the mansion a bit. You still haven't met all the proxies and other creatures living there, as the mansion seems to be nearly endless on the inside. Probably magic or something...

You wander down the hallway of the mansion, just looking around. After a while you hear some strange music coming from down the hallway and you decide to investigate. Following the strange melody, which reminds you a bit of the ones music boxes make when winded up, you go further till you reach a room. You can't remember being here before.. but the door is ajar so you enter the room curiously.

As you go inside you notice it's a bit dim with not much light. There, in the middle of the room like it's completely normal, sits a music box on the ground, illuminated by an invisible light source. Carefully you approach the music box, which seems to just play its melody like nothing is wrong.
