After you leave the Asylum where you do all the tasks with Doctor Killjoy, you will be in an area which has what appears to be a nine-step staircase. Walk up it and follow the wall. Sou should run into an opening that has walls made of some type of vegetation. You will hallucinate and see images of your children. As you follow them, they will run down one way. While continuing to follow them you will encounter a corpse that is sitting up against the vegetation wall, with an axe laying beside him. This is a reference to The Shining, where Jack Nicholson is chasing his son through the labyrinth and dies against one of the walls inside. Note: The Shining was also mentioned in the game's bonus material.
