Meaning of dream, accidental murder and hiding the body?

I had a disturbing dream last night that has been stuck in my thoughts all day. Parts are blurry, but I know that me and some friends were doing something and another friend died, and we knew it was our fault so we spent the majority of the dream trying to dispose of the body. I think when I woke up we were in the process of trying to bury the body in somebody s backyard.

I vividly remember feeling terribly guilty the whole dream and wanting to break down and cry. I was also constantly terrified of being caught trying to hide the body, and hated myself for not having the courage to give my friend a proper funeral.

I have no idea why I would dream something like this. Nobody close to me has died for years. I hardly have any trouble with the law, and I really don t think I have tendencies towards killing people...Any ideas, dream interpreters?
