Being some sort of Emperor looking at a Map of a strange world, I apparantly had lead campaigns and conquered a big deal of other Nations, but I was worried and so were my Advisors, telling me that my Empire was too far stretched for my Military to keep order. Soon after, two other great Nations declared war upon my Nation, to exploit the current weaknesses. In the end of the dream, before I woke up, I was with some of my last loyal Soldiers, making a last stand in my Capital.
Edit: Now that I come to think of it, the dream may have slightly been influenced by the book that I currently read "Mistborn: The Final Empire"
