This chapter discusses reflections on the nature of sleep and its concomitant phenomena. It contains a general review of the observations relating to sleep. Comparisons are made between the dilatation and contraction of the muscles in the body, as monitored in the forearm, and the corresponding inferred reciprocal changes in the cerebral circulation related to the sleeping and awake stages. Changes related to respiration are discriminated from changes related to mental state in these stages. Changes in heart rate are correlated with these states. Conscious and unconscious events are discussed. Attempts are made to determine if unregulated circulatory swings might be related to dreams, while a state of deep sleep implies that conceptual activity ceases.
