I was shot by an unknown man in my home then I "sat" and watched my family being murdered. My mother seemed to accept it.. my father seemed angry and my brother tried to run.

It means you are sorting out the news of the world around you and are worried about the safety of your family. You also have given your parents and brother certain attributes about facing danger based on what you think they might be like.

It's very rare to dream that you are dead. I think Freud said it is impossible (I could be wrong about that). I remember one very vivid dream from about 35-40 years ago in which I was dead, or my perception was that I was dead. At least I understand the contradiction to reason - how you can be aware that you are dead in a dream. But as you know dreams are rarely organized, rational, and reasonable.

I have had many dreams about being dead and about fighting for my life or the lives of my family. Generally, I dream about being dead when there has been a death of someone close to me or when I have been reading/watching something that discusses death. Dreams about fighting for my life can also be prompted by reading/watching material with death in it but more often both types of dreams seem to be triggered by stress. I think perhaps the 'fighting' I am doing for my life in the professional arena during the day translates into literally fighting for my life in my dreams at night.

People have truly bizarre dreams. We tend to dream about the things that are on our mind frequently or right before bed. Dreams are random electrical firings of neurons in the brain. They tend to originate from more active areas (which is why frequently/recently active thoughts tend to feature) and as the impulses spread, more random thoughts get stimulated. Afterward, your brain tries to put all of the thoughts into a cohesive image/story as this is it's natural imperative. I heard and read about this theory many times while obtaining my degree neuroscience.

At any rate, while I do believe the ways in which you interpret information from your dreams are revealing (the attributes you give your family members, how you feel about their deaths), I don't think the content is necessarily anything to worry about (a death scene).
