I saw my earlier selves as different people, acquaintances I had outgrown. I wondered how I could ever have been some of them.
Roger ZelaznyOf all the things a man may do, sleep probably contributes most to keeping him sane. It puts brackets about each day. If you do something foolish or painful today, you get irritated if somebody mentions it, today. If it happened yesterday, though, you can nod or chuckle, as the case may be. You've crossed through nothingness or dream to another island in Time.
