Dreaming about borrowing a car, especially one belonging to someone with whom you recently had a difficult relationship, can symbolize feelings of vulnerability and loss of control. Cars often represent your personal journey or direction in life. Since the car belongs to someone who ended a situationship with you, it may reflect lingering emotions related to that experience.
The act of scratching the car could indicate feelings of guilt or fear of making mistakes, particularly in relation to the past relationship. It may also signify worries about how your actions might affect others or how you are perceived by them.
This dream could be prompting you to reflect on how you handle conflicts and endings. It might be a sign to address any unresolved feelings about the situationship and consider how you can learn from the experience moving forward.
Take time to process your emotions and consider what steps you can take to heal and regain a sense of control in your life. If you feel comfortable, discussing these feelings with friends or a trusted confidant may also help.
