It's actually right on the Swamp King's territory!
Glancing at the scenery of the first layer of the Nightmare World, after glimpsing an endless desolate swamp, the Zealous Miss Snow, who was genuinely envied by several other Nightmare Entities, couldn't help but be overjoyed.
Compared to the nightmares of the Miasma Deep Forest with human-faced ghosts, the Mirrored Empty Blue Sea with green tide sea monsters, and the Boundless Desert with giant sandworms, the Wasteland of Reeds extended by the Swamp King, although seemingly unremarkable, is definitely the most dangerous among the six layers of dreams.
The swamps in the Nightmare World are different from reality; they don't follow the rules of the real world and instead closely adhere to the swamp imagery in the dreams. Once a swamp appears in a nightmare, it mostly represents the irreversible "fall."
