Or I think of breathing - the body in its wisdom taking its sustenance out of the air even when the conscious mind, the will, the hunger both for life and for death, are asleep. I think of the breathing of one who is asleep, how suddenly in some dark passage of the night the breathing becomes a word, the dreamer speaks, and through his word the fragment of a dream passes from inner world to outer world. The visible effects of the invisible manifest themselves.
