In entering sleep you surrender autonomy in order to gain more freedom in feeling and imagination. For all its variety of detail the movements permitted in waking life are highly constrained, and this constraint is frustrating and exhausting. The movements in waking are cut short but in dreams you can 'follow through' even at the cost of being unable to make much sense of where you are or what is happening. What is it that needs to move in this way? The heart? The soul? Whatever it is it seems more real than what you take to be yourself, this unknown thing that you live on behalf of. As if you feed it with experiences, take it on holidays and to shows, feed it with art, religion, as if it is as demanding and incomprehensible as a baby. You are never quite sure what nourishment it craves, what, in short, is the point of experience. There are theories, of course, tacitly understood, mostly social in nature, and therefore entirely vacuous. It is nothing if not entirely inward.
