Mall World 
The Black City (A city of featureless black skyscrapers where it's always night)
The Old Town (A decaying downtown with1940-1950 architecture, dive bars and old style theaters.)
Cold City (Resort town in a snowy mountain setting. 1970's era Mountain is impossibly steep.)
The Beach Apartment (It's always sunset. Warm humid, warm air with beach grass and sand fences. Sun is impossible large and orange. This is the most intense, most lucid one. I can always smell the salt in the sea, hear the waves and the sound of the wind and the cry of birds.)
The Empty Halls (Hospital like or hotel like featureless halls that run on forever. Sometimes has lockers like a school.)


These are the most common but there are others.

My dreams have the following and I'm wondering if you've ever encountered them too.

Infinite City (huge city that has near endless amounts of roads, people, buildings, houses, and parks. Vehicles and structures are capable of mass shifting)
TARDIS Houses (Houses and living quarters that are physically bigger on the inside than they are on the outside)
Big Ranch Resort (Multi-million acre ranch that runs along a coastline, large enough to have both a full-size airstrip with an airport and a passenger ferry service. Mansion that's at least 10 floors)
