What does it mean to dream chopping your sister into pieces?

Although this dream seems excessively violent, its meaning is completely benign. If the dreamer is female, the sister most likely represents the self. The chopping is the way the subconscious mind presents a vivid metaphor with a literal picture. We all use figures of speech that are not meant to be understood literally: "she was torn apart," or "she's falling to pieces." The message in this dream is that the dreamer is dividing her life into pieces in some way. It may be by taking on too many conflicting tasks, or by trying to please too many different people. There is the sense that she cannot give her "whole" self to any one thing. There is also a strong message that the dreamer is harming herself by being divided instead of being focused.
