To dream of assassinating someone signifies repressed anger, aggression, or deep-seated resentment towards a specific person or situation. This dream may suggest a desire to eliminate or get rid of the perceived threat or challenge in one's waking life. It may also reflect a need for power or control in certain aspects of life. Additionally, this dream could be interpreted as a symbol of internal conflicts where the dreamer wishes to "kill" certain negative traits or thought patterns within themselves. Consider the identity of the target and the feelings experienced during the dream for a more accurate analysis of its meaning.
