^You stand in the middle, looking outwards and inwards at the
  same time. When the two are the same - (what you think you see,
  you actually see) - everything is in flow and is smooth and
  there is no sense of time passing.

  But when there is an XOR - when there is a different in the
  images between what you think you are supposed to be seeing and
  what you are actually seeing through your senses, the overlay of
  the two images has a complicated thing that just doesn't make
  sense.

  That tiny part of your brain where all consciousness passes
  through, from inside and outside simultaneously - has to
  calculate Truth from it and what to ignore. If the different is
  too great - too big for that small part of the brain to chew on
  and digest, it rejects it until it can find a preexisting
  analogy in the brain to attach it to. That's why it sometimes
  takes years to figure out what happened to us as kids, or why -
  or if - we were rejected by someone in our lives, or whatever
  extremely "doesn't fit" thing happens.

  Even babies need pacifiers to be consoled. The world is tough
  right from the start. But if you've made it this far, your
  chances of carrying on, are pretty good.^
