You start by "listening" to your body, you tune yourself in to the frequencies of your organs and muscles, and you wait.  You grow bored with that quickly and begin thinking about other things.  Perhaps you smoke a cigarette or twiddle your thumbs.  You begin to grow dispondent over the whole night.  You feel cheated and start to grow angry.  If you're sitting you stand up, if you're standing you sit down. 

  For a moment you contemplate going to bed, but suddenly this feeling begins to grow in your belly.  Like a giant anchor that is now lodged in the Earth making movement damn near impossible.  You look around, the light is there, the walls are there, your furniture with your tv and your shelves containing books and movies, the tacky nick nacks on the wall and the poster you thought was cool 2 years ago.  But now they are not simply there, they are THERE.  And the more you stare into their souls the more you see of yourself in them.  And when they begin to look into you, and they find no soul and question you, you look away. 

  You see yourself again, a wild jutting artifact of electrons and protons and neutrons.  You are an alien, not only to the world around you but also to the world inside your head.  Something snaps.  Your eyes grow wide, and you begin to breath heavy and sweat.  If you are sitting you stand, if you are standing you sit.

  You have to move, your body wants to move.  It does whether or not you want it to.  You can't control it anymore, because you realize you never had control.  All senses are failing because for the first time they're working.  Acceptance is the only answer, that or go mad.  So you accept your current and permanent situation. 

  And that's when you notice the bug crawling on the floor.  And you are happy, for the first time and forever, you are truly and sincerely happy.
