Never Happened I.
We are all born with the gift to see and hear and we keep suppressing it as we grow up. The adults tell their kids that what they see and hear is not real. And these kids start to believe it and replicate this pattern later on with their own kids, and so it goes on and on.
We all deliberately decide to force the fantasies out of our minds and forget what was so obvious and effortless to us when we were young.
