"Your emotions are meant to fluctuate, just like your blood pressure is meant to fluctuate. It's a system that's supposed to move back and forth, between happy and unhappy. That's how the system guides you through the world."

I feel more and more as if time did not exist at all... only various spaces interlocking according to the rules of a higher form of stereometry[the geometric measurement of solid bodies], between which the living and the dead can move back and forth as they like, and the longer I think about it the more it seems to me that we who are still alive are unreal in the eyes of the dead.
