I had a dream that I was trying to take over a castle and overthrow the king. It turned out that I was a distant member of the royal family, so the magic castle responded to my wishes. With a slash of my sword, I could cut through the walls. Or I could repair the walls. They tried to convince me that, since I was a member of the royal family, I should put down my sword and join them. Instead, I slashed my way to the upper floors of the castle, looking for the king. I went higher and higher, until I was on the top floor, and then I went even higher, into levels of abstraction. There was a map of the castle. I slashed higher. There was a schedule, showing the planned activities in the castle. Finally, I went high enough that I found the very idea of hierarchy and destroyed it!
