dream fragment

OK, this was an epic dream of mines which i can only remember a fragment of now. It's starts with me being in my house and being on the computer, Then suddenly combine from hl2 invade america and starting blowing up houses in my neighborhood with Russian bmp's. I tell my parents to duck and i randomly pull out a laptop and call an air strike. After the air strike the bmp starts blowing up my house, my parents die and i run through backyards evading explosions and other randomly epic stuff.
