"Let's suppose that you were able every night to dream any dream you wanted to dream. And you would naturally, as you began on this adventure of dreams, you would fulfill all of your wishes. You would have every kind of pleasure. And after several nights you would say, well, that was pretty great - but now, let's have a surprise. Let's have a dream that isn't under control - where something's going to happen to me that I don't know what it's going to be. Then you would get more and more adventurous and you would make further and further-out gambles as to what you would dream. And finally, you would dream where you are now."

 - Alan Watts
