dreams, dreams, dreams

I woke up from a dream where I'd been stuck inside a car, trying to get home, and a man who'd been following us and giving out three warning shots went on to shoot the driver, then my friend, and then me, and I couldn't do anything to stop him. I didn't even know why he wanted to shoot us.

I've looked guns up in dream interpretation sites, but any idea how the dream as a whole could be interpreted? :|
