What is reality?

What is reality, in which we dream? Or do we dream, we are in reality? What makes life real, and what makes it a dream? How can we decide for ourselves, which is which?
Is reality what we expect it to be? Or what others expect it to be? Can we really call it reality, if we aren't being 'real'?
Can we pretend we're in a dream, with everything we ever wanted, in it? Or go about our normal routines, and not dream at all? I dare to dream. And I dare to make my dreams a reality.
Can we continue living our lives in a world that dreams so little? Can we continue accepting what isn't really real? Or must we dwell on the fact that our dreams make our reality?
