The subconscious runs the entire show. We only become conscious of 'things' whether visual, auditory, or mental, because our subconscious allows us to. I've never considered my subconscious a dark place, but it can seems so to others to whom it operates as a black box. With some effort over the last 20 years I have substantial access to my subconscious that I never had before. Our consciousness is but a thin veneer on our subconscious. Once we accept that, lots of behaviours, thoughts and feelings, become both understandable and accessible.
