In your dream, the area you are in represents a pattern of thought. Since this is a 'bad' area, this shows that you are in a nevative frame of mind (for the message of this dream). Your friend represents a part of how you think. Look at her personality. The way you would describe her is that part of you being addressed in the dream. (Is she uptight/relaxed?,honest/dishonest?, self centered/selfless?) Walking with her and then her running away shows indicates the kind of thinking you were using that may have brought your mind down with negativity. An example of this would be a 'woe is me' attitude. Death means change, so getting shot in the head shows a potential of being changed. All the panic involved shows a lack of preparedness...as if you were suddenly faced with the results of your negative thinking. Look over your life and see where you have recently found yourself surrounded by negative thinking. Nervous, sad, angry, jealous...these are some types of thinking that could bring you down to a point of changing who you are. Look for ways to find the positive. I hope this helps. God bless.
