Mebediel, I understand that feeling (also, the moving castle idea seems really cool, even if it might not work in-universe). I'm starting to feel more at home in the city after living here for a year and a bit - it's a completely different landscape even without the buildings, with the sandy soil and the scrub-covered limestone ridges, the lakes and swamps, the ocean with all its different moods and patterns (the ocean is warmer and friendlier here, and the coastline is smoother) - but as I spend more time here I get to know it more and I feel more and more comfortable (it's not as beautiful, but there's a certain something to it nonetheless). Part of me wonders whether a dreamworld would no longer be in my old town (which is full of bad memories as much as it is full of good ones), because I prefer living here. Yet whenever I go back down south, there's a part of me that yearns to stay with the tall forests and the cooler air and the tiny wildflowers in the leaf-litter and all of that which I know and love.
I miss the land far more than I miss anything else about that place (because there is so much that I don't miss).
If I were to have a dreamworld here, it'd probably be down by the ocean - near the old abandoned power plant, maybe, where there's some weird lakes with surprisingly big fish in them (used to be drainage, I think), before you follow the dunes down to the ocean and the remnants of an old grate are a bridge across the beach. Or maybe one of the weird limestoney hills (one of them has some old-growth tuart forest that's really cool) - the view is amazing and there also always seems to be some weird ruins of like, a wrecked car or some long-lost building's foundations hidden among the trees and the scrub. One time we also found a small cave.
