Psychologically: If one kills or shoots in the dream a known person, expresses these suppressed fury feelings which one has edged out in the everyday life, which give vent now symbolically to themselves. If one is murdered against it himself by somebody or is attacked, this certain person puts unattainable expectations of you in your life. If one cannot fulfil the wishes, demands or expectations more different, debt complexes arise. The unconscious often abreacts by aggression attacks this 'internal pressure'. (See also steam)
