I don't know. My own dreams are fairly mundane. There can be surreality, but it's the sudden change in place or people swapping in and out surreality, not blatant Dali-style stuff like you're describing. I can only remember one off-hand that was even close to the city folding in over itself (the undertow of a large boat in the water feature behind my house pulled the ground out from under it, so the house capsized in the water and I had to rock it back right-side up. See, that even had a rational underpinning).
