"We all possess, in our unconscious minds, a kind of servant who performs certain automatic functions. When I learn to type or drive a car or learn a foreign language, I have to do it painfully and consciously; then, suddenly, my robot takes over and does it automatically; in fact, he does it far more quickly and efficiently than "I" could. The main trouble with this mechanical valet is that he often takes over functions I would prefer to keep for myself - for example, when I am tired I eat "automatically," […] In fact, this is the reason that so much of our experience seems oddly "unreal"; the robot has taken it over. […] I may live for whole days in a "robotic" state, so that experience flows off me like water off a duck's back."
