angie - you have an excellent point. Our "falsehoods" are
  completely authentic in a weird way. It's like your mental image
  of other people: Nobody REALLY knows what another person is all
  about - they can just look at the traits, mannerisms, habits,
  things they say and come up with a judgement of what they THINK
  the person is all about. But they don't really KNOW. Or when you
  dream: the characters in your dreams are just aspects of
  yourself, portrayed as other people. "
