A dream of war and tsunamis?

Last night I dreamed that some country (not sure which one) started dropping bombs in Michigan (I live in Michigan). I was with a bunch of people and we all started running to find a safe place. Bombs kept going off right next to me. All of a sudden I found myself at my step dad's house and a huge tsunami was coming towards the house. I got in my car and drove as fast as I could to get away. I tried calling my sisters and my step dad to see if they were ok but couldn't find them. I called my mom (who now lives in Texas) and she started to panic. Suddenly my sister called me and said she was safe at work and so was my step dad but my other sister couldn't be found. Next thing I know I was at the house again and went inside. I looked out the window and I seen my sister, her dog and her cat sitting on a raft on top of several feet of water. I got her in thru the window and we were all safe but I said to her "Maybe the end of the world is coming". Then I woke up. I'm a strong believer in the paranormal but I don't believe all the mumbo jumbo about the world ending. What could this mean?
