Imagine that every night, you can dream anything you want for as long as you'd like.
And on one particular night, you decide that you will dream a dream that will feel like 80 years of time.
So for the first several months of this dream, you are a god of this dream of yours, fighting dragons, police chases, planetary war. But then you get bored. You can do anything you want, feel anything you want, and you get oh so very bored.
So you create a button labeled "surprise". When you press this button, anything could happen. When you press that button, you may find yourself in an unknown land, in a different body, different surroundings, different memories.
How do you know that you didn't just press that button?
