Our perceptions are fragmentary. We build compilations of our perceptions into theories of "reality." We can alter our experience of reality in many ways. The foundations we make based of some of these altered states can augment and/or detract from our being able to function in a world based of the connection of random yet intentional perceptions. These constructs are reliable in the short term, but need to often be corrected. Don't get stuck in a singular point-of-view.
