All there is, is how you perceive things. Reality is the real
  you make it. A shared reality is when a group has a similar view
  of reality - the muslim hatred after 9-11, a couple shares the
  same dreams for a house or a better life for their children -
  its a perception of reality. But what's really "real"?
  Objectively, I can't say. Hopefully before I die, I'll have a
  better answer! "
