Imagine someone running. Now freeze him in place. How is he positioned? Now stand up and reproduce with your body the pose you've pictured in your mind. It doesn't have to be perfect, just capture the essence. Are you doing it? Good. Now where are your arms and legs? Are they where they should be?

Close your eyes and touch your nose. If everything is working properly, this should be easy because your brain can sense your body, as well as its position and movement through space. This is called proprioception. But how does this "sixth sense" work — and what happens when it clashes with other senses?
