Here's another one for you - reality in your mind is simply your perception when your senses deliver the electrical impulses to your brain. They are perpetually "late", due to physics of our universe. Therefore, someone with an agenda could be shaping your reality every second to present you with a "fake" one. (If you even begin to believe that, or try to use it in a rebuttal to me - consider getting some professional help.)
That is a such a philosophical oriented comments, what do you mean here, could you elaborate a little bit?
