In the land of Liminal Space, you're known as a Spirit of the Overworld, or a "Patient". Under circumstances of how you got there, it was a "Dream" as the land put it, something engraved in your mind vaguely. Liminal Spaces are the areas/rooms that evoked nostalgia or uncomfortableness, even if its not physically damning. The areas and rooms can lead to another, the aesthetics changing to fit the Patient(s)'s mentality and psychological thinking.
