Dreaming about an ex-girlfriend yelling at you can symbolize unresolved feelings or guilt related to the past relationship. The act of her accusing you of emotional abuse may reflect your own fears of having caused pain, whether intentional or not. It could also suggest that you are grappling with feelings of regret or a desire for closure regarding the relationship.

Her changed physical appearance may indicate a shift in how you perceive her or your past together. This could also represent your own growth and changes since the relationship ended.

Overall, this dream might be prompting you to reflect on your past actions, take responsibility for any hurt caused, and consider how you've grown since then. It may be beneficial to think about what you can learn from this experience to foster healthier relationships moving forward.
