This dream may suggest that there is someone in your life who isn't genuine and is pretending to be someone they are not. Your subconscious mind might see them as a threat and it is showing you that you need to deal with this issue. The precious person in the dream could represent someone or something that is very important to you. Fighting and ultimately killing the impostor within your circle may signify that you are taking steps to confronting the person and exposing their true nature. Alternatively, this dream may also indicate that you are taking charge over a situation or issue that has been bothering you for a long time and that you are determined to resolve it once and for all.
