Sounds like a cool dream. I love dragons. I dream about them quite often. The metal architecture sounds really neat. I love dreaming about cities. especially when I'm flying over one. Cities look really cool from high up places. Too bad you can't remember the other dream. That happens to me lot. I like to keep a notebook close by so the dreams don't fade from my memory so fast. I'm not always thinking about my dreams when I wake up though. They say it's good to keep a journal of your dreams.
