There is a sort of waking nightmare that sets in sometimes when one has missed a sleep or two, a feeling that comes with extreme fatigue and a new sun, that the quality of the life around has changed. It is a fully articulate conviction that somehow the existence one is then leading is a branch shoot of life and is related to life only as a moving picture or a mirror - that the people, and streets, and houses are only projections from a very dim and chaotic past.
