Scavenging the Landfill of the Unconscious

Dreams may derive from profound (or absurd) psychiatric origins such that only a Freud or Jung could compose suitably profound or perverse theory. But in my dream-state experience (which exists often while I'm awake), I find that perhaps the most prolific source of dream imagery is . . . a landfill dumped-in by the conscious mind for later random (or worse) picking!!!
