Psychological Meanings:

Suppressed anger inside you You killed or shot the known person in the dream, this expresses suppressed anger feelings which you have edged out in the everyday life. On the contrary you are murdered  or attacked by somebody you know, this certain person has unfulfilled and impossible expectations to you in your life. If you cannot fulfill the wishes, demands or expectations more because of others, then responsible complexes arise in your dream. The unconscious often responds by aggressive attacks from “internal pressure”.
