Consider the source of all painting, cinema, music, performance, and literature.  Genre notwithstanding.  The source is Self.  Life.  Details, echos, remembrances and references of our "real" life, midwifed into creation.  Conscious or not, narrative or not -- art is always about what we're going through at the time.  Acclaimed writer Paul Auster probably disagrees.  And he should.  As this author of iconic literature - including five memoirs (!) - has always been in the eye of the self-reflexive storm of creating, he would only feel its calm.  Assuming there is one.
