Please interpret my dream?

In the thirteen years of my life, my dreams are mostly unpleasant and gory just like the other day when i saw a person hanging in our school building with it's face seperated from its body. (i dont watch horror movies by the way because im easily freaked out) Last night my dream occured in London. I was standing above the water (river thames i think) fire were falling from the sky and the buildings are all burning. There were gunshots everywhere and people are running for their lives. I also caught a glimpse of prince harry and another man standing on a collapsing bridge.
