In all likelihood I am in a coma and none of you are real, or hooked up to the matrix, or a brain in a vat, or even a computer program designed to think I'm human. Taken at face value these thoughts are rather disturbing to me, but look a little deeper and you will see they offer some comfort in the possibility of an afterlife, and an involvement in something bigger than the seemingly insignificant lives we live out on earth. In any case, life and the human mind are truly bizarre phenomena. Bizarre and wonderful.
