Subconscious, is when we like to program ourselves to remember something or to do something. It is also a child-like spirit in its playful ways.

Unconscious, is a sub-level below our Subconscious, its conscious-unawareness. It's when we totally forget due to time, or its to painful to want to remember it(trauma), repression, yada yada.. "Don't go there you'll only bring out the BEAST in me!!"
