Having a vivid dream does not mean that it's a prophecy for the future, Edb123. I think that you also stated that you've heard voices since then telling you to tell people about it. Still, it may not be a prophecy. I don't think that you are lying, Edb123, but what you dreamed about doesn't line up with Sacred Scripture, as has been pointed out to you, but you're not addressing it.
When Noah was told to build the ark, he told people why he was building it, but I don't recall that he berated those who did not believe him. He was a just man, and had no need of name calling.
I've had vivid dreams myself, but they did not portend the future.
