I guess it depends partly on the exact definition to the first two levels. Would the awareness of knowing that you don't know everything be a merely level 2? Would there be a line between what you know and an intuition or gut feeling of something you don't really know know but have a feeling about? Is it possible to go outside of your body to know at a greater level outside of the five or six main physical and tangible senses that we are generally aware of?
