A Dreamers Mind

If dreams could become reality, would this mean that the reality we perceive becomes a dream we dream, or maybe that dream is just a fragment of a reality in which we have already lived before it became a dream. Therefore is reality real or a dream within a dream, which you never awake or realise you are awake. So when you do wake, are you awakening from a reality or a dream. Just maybe then, what we see is a dream until we sleep to live our reality.
