What is reality?

What is reality really? Could it be that we are all in a long drawn out dream. I mean our sub-conscience could be what is causing us to live and to keep going. Our sub conscience controls us of everything we do and don't do. Think about it. We follow laws because our sub consciences tells us if we break them it will be wrong, whether we do it or not. Our brains function around sub conscience thinking. Our sub conscience has a mind of its own. Ever think about the voice in your head that you create to make it sound the way you want it to? You want it to sound like the voice you dream of having.
