Interesting thread, My LD 's have always been in the same places, I figured it was a normal, at least for me. I actually compiled maps and descriptions of each "zone" in my dream world, Some places are from when I was a child and some newer, so it is ever growing. Each can be reached from the other by some means of travel, so it is very similar to this world in the fact it has distinct geography despite that flux that occurs in some zones. These places include huge cites, desert wastelands, oceans, ruins etc. The majority of buildings are dilapidated and abandoned, some times with unpleasant guests/entities, so it can be a very creepy setting,
