When you dream of lashing out, it symbolizes repressed anger, frustration, or a sense of powerlessness in your waking life. It suggests that you may be harboring pent-up emotions that need to be released in a healthy manner. This dream can also point to feelings of being unheard or the need to assert yourself more assertively. Consider the context of the dream and any specific individuals or situations involved, as this can provide insight into the source of your underlying emotions. Reflect on ways to address and communicate your feelings effectively to prevent them from manifesting negatively in your waking life.
