To me, nothing is real. I'm afraid I'm with Rene Descartes, I have doubted everything I thought I knew to be true, but once I did, I found that all I can truly know without a doubt in my mind is that I exist. Does that mean that I am really here on Earth and my being is this very human form in which I can taste, feel, smell, see, and hear? No, I could be in another dimension being fed data streams through a computer telling me what I am perceiving to be true, just like in the Matrix. I just cannot prove anything. I am not in control of my self, there are many things controlling me, such as my physical body, my personality, things that happen trigger chemicals in my brain, and other people.
