We don't have direct access to our OWN experience's. The flaw is
  assuming that somehow we do. The brain is an outcropping of the
  nervous system It is part of the same nervous system that pain
  is.
  A story told, by whatever means, that engages the
  listener/reader/watcher/whatever into replacing their "me" with
  the "me" of the character through suspension of disbelief, and
  YES, you can feel their pain. Shared subjectivity.
