I quite like this.
People might disagree with me, but I think of reality as a subset of existence. All things exist, including things that are not and cannot be real. Reality consists of all the things that can have an impact on us, be impacted by us, or have an impact on or be impacted by another real thing.
What I think is most awesome thing about being human is that we can imagine things that are not real, and create a real concept of the thing, bringing it from outside of reality, into reality (in a sense). Our power to do this is not absolute, but it is awesome.
