Of course, life in general perches precariously on the unknown. Any moment could be our last. But somehow when we're awake and move through our day, we seem to be in control of our own mortality, or at least feel that way. But when we sleep, when we close our eyes, we submit our life to the great world of the unconscious. If we surrender to death while we sleep, it is unlikely that we will even be aware in the moments before, as opposed to dying during wakefulness.
