Bad dream

So I had somewhat of a nightmare last night, I was sitting in one of my classes (It isn't an actual class I have) and the professor was this large bald man with a tan tint to his skin, thick glasses and extremely blue eyes. He also had a light German accent and a very deep voice and when he would talk he would get in your face. Anyway the dream was me sitting in the classroom and he was going on a rant telling me about how people are evil and how there is no good in the world and when he would say thing like how people are evil there would be images flashing through my head of people doing evil things throughout the world. He also told me how America isn't the strongest nation anymore and I saw this satellite in space that the U.S. shot missiles at but we couldn't blow it up and after we stopped shooting at it the satellite shot a beam down to earth and blew shit up like cities. Then after that the professor man told me that the only reason governments existed was the start wars and keep the world population from getting too big and I saw soldiers going around killing people.
All in all it was a pretty shitty dream.
