So I could be standing atop an Aztec temple dressed in priestly robes with thousands of naked women throwing little pickles at me if only my mind were free?

(You may think that's cute, but do you get the reference?)
Your theory implies that people whose minds are free of constraints could bend reality to their will. In other words, if you truly[/B] believed you could, say fly, then you would, in fact, be able to fly. Well, people under the influence of hallucinogenics sometimes believe just that (you occasionally read about them taking swan dives out of high windows) and yet remain subject to the laws of gravity and physics like everyone else.
