Of all the thoughts that pass through my head before I fall asleep, this one was worth the draw.

He lives in two dimensions simultaneously - the "real" world and this one which only he can see. Both worlds have creatures that the other can't see but it affects both every now and again (think of that one episode of Adventure Time where Finn touches the lamb and gets sucked into the Spirit World). This kid is definitely the reluctant hero here though.
