Dream i'm being shot?

I keep having an incredibly vivid dream where i'm in Yemen helping these kids I don't know audition for a musical, then I step outside the building and I'm shot (and presumably others too) with a machine gun repeatedly, I have to lie in the dirt bleeding, pretending to be dead until they leave and then I stagger along a path, cursing Amnesty International and trying to find someone to help me and the others because I'm convinced I'm not going to die? I've had this for three nights now and I've never had a dream last more than one night before, does it mean anything? How can I make it stop?
