Poetry.
"Poetry and sleep have always been related to me. What do we seek when we lie down to rest but a pleasant landscape of language? inaudible rehearsals of the auditory, invisible practice of the visual.It is possible of course to be asleep and awake at the same time, indeed we are mostly, examples: driving the freeway and missing the exit engrossed in meditation, orbetter the ineluctable state of napping in my chair, when I leave me there and go out for closer observation, hearing even seeing everything that goes on around but not noticing my own snores" (from the Introduction by the Author).
