Am I going to die soon?

I had a very strange dream last night, in which I was in a bright room and two of my dead buddies from my platoon came in and brought me a black suit, they both looked handsome, clean and where in a good mood. We talked for a while (can't remember about what) and later they gave me that suit and told me to keep it, because I will need it soon. Then they invited me in, and I woke up next to my wife, and fell asleep again. In ten days I'm going back to Afghanistan and now starting to freak out. My grandmother told me a story, about how she had a similar dream of her mother. She gave her a black suit, but my grandma told her, that she won't need it, but her mother told her it was for her husband Vytas. In the morning he drove to a small town, because he had some business to take care of, and there he was killed my partisans.
