I enjoy surrealistic art and sculptures. The juxtaposition of incongruent objects or strange settings towards creating a sense of the dreamlike or mysterious. Reality, even its it most mundane moments, often presents surrealistic moments. Once I saw a shopping cart in a field of pumpkins. The Cadillac Ranch in the Texas panhandle is an exploration in the surrealization of everyday objects. See below..
Though the brain be made possible by the regularities, restrictions, and contradiction avoidance in nature's governance... It certainly has little interest in making its own dream worlds conform to the external universe's version of sanity.
