I wanna co-write it! Okay so it could be a character that appears on your screen if you've been drawing for too long, late at night and if you try to erase it, it seems to get closer and closer to you. And when you finally erase it, the person falls into a coma, and when they wake up, they're basically brain dead except for the fact the they mumble, and draw the creature over and over, on every surface they can.
