treas-on different words to Dream on

I hear different words to songs this one are a different take on Dream on. Some times its like a great song with an evil edge or origin can be , shall we say redeemed perhaps. And since the original song has a dark or questionable edge to it, the new words give it a Good , true good over evil take now. So the evil appears through out the new words as well it is less veiled though neither is the hopeful outcome.
