Lego City, by Bill
In my dream, I visited a landscape version of Hollywood that I’ve been building and visiting for the past 4 or 5 months. I much prefer the dreamscape to the real hollywood now. I discovered that certain, if not all, buildings are lego-based, meaning they can be picked up by some god-sized hand and set down and snapped in place in a different part of the city, thus rendering useless the dependence on such structures as bearing-providing landmarks.
There was also a really neat thing where all the citizens of the town had to return their garbage to a store-type place. Once you were done with a bag of potato chips, or a six-pack of soda or what have you, you had to take it to a place and put the trash back on the shelves in order, just like a supermarket in reverse. it was really fun and everyone did it.
