Can someone please interpret this for me

Ok so I don't remember my dreams that often and when I do they're usualy just pretty neat. But this one really got me thinking. I had a dream that the Russians were attacking us and they were winning. They pretty much took over 3/4 of the world. Everyone in my immediate family was in the dream minus my older brother. We all lived through the innitial attack. They let us live saying that the 2nd wave of attacks would kill us so there was no point for the soldiers to kill us at that time. I saw tons and tons of dead bodies lying around. As everyone was scrambling around to figure out what to do, out of nowhere my younger brother jumped from the building we were near to his death, he was about 20 or so stories up my mother and myself watched someone jump and I said to her that it was "michael" (brothers name). She started crying and said "i don't want to see the body" I told her she didn't have to. We told my dad and he started crying ( he never cries ). But for some reason I wasn't that upset although me and him get along very well. We talk almost everyday or play video games on the computer almost everyday. Oh by the way he dosen't live with me and hasn't for many years. But after he jumped to his death, we started to take back over America but it was weird it was like a video game now I could see on tv where we were building and where the fighting was going on and could actually see vehicles and structures being destroyed on a screen. But what does all this mean? the war my brother jumping to his death everyone crying except me.
