Since the thread is pretty much exhausted, what I had in mind for that one is a kind of "cheat code" for reality. It would be a key built into the program of our lower-order reality.
So, something like, "If you imagine yourself wearing a purple laurel wreath upon your head and the red robes of a Caesar, your chances of winning any game will increase by plus ten percent."
What I had in mind for the perfect health one was: in your dream you learn a dozen yoga postures and ways of deep breathing. After practicing them for ten to thirty minutes each day, all diseases and injuries are cured, heightened detoxification takes place, and you rapidly reach your ideal weight. If you wear eyeglasses, you no longer need them.
However, dietary restrictions of some sort would also be a part. Obviously, you can't attain perfect health scarfing down Twinkies and Ho-Hos.
Open question whether or not the secrets work for others or not. I hadn't considered it. The cheat code might be a general one, or specifically keyed you personally.
