Psychology: Killing people is an extreme way to solve problems. In some cases, such a dream may appear, and the only feasible way to solve the problem is to "kill" a part of yourself.
Spirit: On the spiritual level, the killing behavior in the dream is equivalent to the sacrifice made to change oneself. So there is no good or bad. The dreamer should compare these with recent events from a spiritual point of view. There are some small things that I didn't care about, but they have become other forms and are reflected in my dreams. don't worry
