i think reality is that feeling you get when you realize that most people wont care about some bacteria found in a hole on mars, because it's not relatable to their idea of 'life on mars' or 'extraterrestrial life'. Many people do not care about reality, they instead live their lives out seeking validation for thoughts and beliefs that are shaped like 'life on mars' and also being afraid that their beliefs might not have any substance. Reality is when you step outside on the road and actually experience how that road outside of your garden hut in some very tiny place is connected to Via del Corso in Rome or to Avenue Gustave Eiffel in Paris. And you have to experience that road to feel that sense of reality. It can of course be smaller in scope, but scope is what provides perspective.
