I understand your viewpoint, and I don't oppose it in principle. It may be applicable to many cases. However (there has to be a 'however') in the instance I have in mind there were, between the time of the dream and the real event, amid the chaos of a myriad phenomena, a number of unforeseeable major events beyond individual control that lead to a completely unexpected outcome. While I'm not devoted to the idea of precognition, assuming it may have some yet-to-be-discovered scientific basis, the extreme complexity and volume of information required to account for such a prediction makes your theory no more plausible. I don't rule it out, but I fail to see how any form of mental analysis could produce such predictive power. There are too many unknown factors - 'unknown' by any currently understood means, that is.
