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.
The meaning of the dream depends on its emotional tone (fearful, happy, sentimental, etc.) as well as the content and context of the dream. For example, a dream about watching the sister drive away in a car would be very different from a dream of baking cookies together in granma's kitchen. Very generally, the dream expresses the dreamer's own feelings; it provides no information about the sister or her feelings.
This dream suggests that the dreamer feels a sense of guilt concerning the sister. The dream is not predicting any future event.
