Reality is such a funny concept since it doesn't seem like it can ever be fully grasped by anyone due to the limited and subjective nature of our senses. I mentioned in the forum a couple weeks ago the top down nature of perception, where our long term memory helps determine not only what in our environment we even notice, but also how we perceive everything that is able to grasp our attention. Both our experiences and culture can change how we see our outside world, adding yet another confound to our perception of reality.
