This sounds like an inverse of the plots for movies like Nightmare on Elm Street, The Matrix, and Inception, but its true. What you experience in your dreams can be directly linked to your physical state; for instance, if you are thirsty or have to pee in actuality, your dreams may rewrite themselves to inform you of this. You might run to the nearest dream-urinal, or start drink¬ing from some hose which may have appeared out of thin air. Also your cravings tend to manifest them¬selves. Ever dream about some kind of desert you haven’t had in a while, and ran out to buy it after being prompted by a dream? That’s the magic ofthe R.E.M. cycle, a.k.a. the harbinger of sweet temptations.
