Liminal Spaces in Pokémon Games

Liminal spaces are thresholds between two places, times or conditions. They're not meant to be stayed in; they're transitory, unnaturally empty, not often given a second thought. They might invoke feelings of unease, or even nostalgia. You can interact with these locations to note their existence, but in a way that leaves them feeling ethereal, dreamlike, or somehow less than 'real'.

The Pokémon world has its fair share of these areas. Can you name those pictured below?
