Apart from the anonymous fat people being imagined by Spades, we have Dreamy Steve who until recently was trapped in the dreams of Ace Dick, Sapphire Dick and the whole Dick family. He is no longer there.
Main antagonist Nightmare Stephanie was and still is in the dreams/imagination of Dreamy Steve. The only way out of this Nightmare Realm is through the door, which only opens from the outside where Dreamy Steve is.
