In dreams you can have the feeling that you've had this dream before, that you have this dream over and over again, and you know that it's really nothing that simple. You know that there's a whole underground system that you call 'dreams,' having nothing better to call them, and that this system is not like roads or tunnels but more like a live body network, all coiling and stretching, unpredictable but finally familiar - where you are now, where you've always been.
