Well, I've been reading "Everything Lucid Dreaming Book" by Michael R. Hathaway, and I read something in this book that I've also heard many people say; the fact that when you are lucid dreaming, that you can go to places you've never been to before. Like, say the Wall of China. You've never been there, you've never seen it, but you can visit it in your lucid dream. How is that possible? I mean, if you have no 'data' of the place, how can your mind create that image? Thanks!
