Reality is the sum or aggregate of all that is real or existent within the universe, as opposed to that which is only imaginary, nonexistent or nonactual. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown.

What we control, and where we really start to create our reality, is in how we perceive/interpret/think about the events in our life that generate our feelings about those events, and how we subsequently respond with our behavior.
