dude it`s the same as the prophecies. You just cant see it. I can dress the prediction of war etc in fancier words and maybe in poems too, but it dosent change the idea of them. They are describing something that (even if they meant it) was true. 1. how do you know that they really meant communism? (for example, you can intereprate it as you wish) 2. even if they came true (some of them), there is no way to prove that it just wasnt lucky guess, or some random guy writing random stuff. To gain followers to his religion or to say something someone want to hear..etc.
