"We live now in an information technology. Flowers have always lived in an information technology. Flowers gather information all day. At night, they process it. This is called photosynthesis. As our neocortex comes into full use, we, too will practice photosyntesis. As a matter of fact, we already do, but compared for flowers, our kind is primitive and limited. For one thing, information gathered from daily newspapers, soap operas, sales conferences and coffee klatches is inferior to information gathered from sunlight.... Either because our data is insufficient or because our processing equipment is not fully on line, our own noctural processing is part-time work. The information our conscious minds receive during waking hours is processed by our unconscious during so called "deep sleep". We are in deep sleep only two or three hours a night. For the rest of our sleeping session, the unconscious mind is off duty. It gets bored. It craves recreation. So it plays with the material at hand. In a sense, it palys with itself. It scrambles memories, juggles images, rearranges data, invents scary or titillating stories. This is what we call "dreaming"."
