Self... what does that even me?

What makes a person? Does self awareness? Does the perception of us in others?
If you lose your sense of self does that mean you do not exist?
Are you just a soul stuck in a body you are not aware of? Trapped in a place that is unfamiliar, uncontrollable?
What is your quality of life then? If you are constantly controlling yourself, an unable to properly communicate due to lack concentration, does it take away from your quality of relationships?
What about outer body experiences? When experiencing them do you feel non human, something of higher power? Are you human, or part of something else? What makes us human, control of the body we live in? What makes us able to figure out the difference between one another if we had no sense of self? Would we not be united as one whole? Is that the only way we will have "peace", or would there still be issues? What is the concept of self? What does it include, our morals, body, thoughts...? Why do we strive to have a different self then everyone else? Can you define yourself? Is it difficult or easy? Why?

Sorry for not posting, so much for the picture a day for a month.. I might try a picture each week and see how that goes.
