What does it mean when somebody you know get shot in your dream?

Dreams often are overly dramatic and exaggerated. In this example, the shooting could represent an argument or discussion in which someone's opinion was "shot down." Other people in dreams frequently represent some part of the dreamer's own personality. So this example could reflect the dreamer's feeling of being "shot down" or defeated at work, in a relationship or some other area of life.

It usually means that the person is not worth staying in your life, and or it means that the person is guilty for something.
