Two Worlds

"There are only two worlds - your world, which is the real world, and the other worlds, the fantasy.  Worlds like this are worlds of the human imagination: their reality, or lack of reality, is not important.  What is important is that they are there.  these worlds provide an alternative.  Provide an escape.  Provide a threat. Provide a dream, and power; provide refuge, and pain.  They give your world meaning.  They do exist; and thus they are all that matters."

- Neil Gaiman (The Books of Magic)
