Dreams involving conflict and resolution, such as the one you described, often reflect underlying emotions or situations in your waking life. Here’s a breakdown of the key elements in your dream:

1. Nighttime and a Party Atmosphere: The setting indicates a social environment, but the night symbolizes uncertainty or hidden feelings. It may suggest that there are issues in your social life or relationships that you are not fully aware of.
2. Fighting: This could represent internal conflicts or disagreements you may have with others around you, possibly friends or peers. It may also indicate feelings of being caught between two opposing sides or issues in your life.
3. Not Joining the Fight: Your choice to not participate in the conflict could signify your desire for peace and harmony. You might be someone who prefers to mediate or avoid confrontation rather than engage in drama.
4. Shaking Hands and Hugging: This act of reconciliation indicates a desire for resolution and connection. It suggests that despite the chaos, you value relationships and are open to making amends.
5. ASAP Rocky and Your Girlfriend's Car: The presence of a famous figure like ASAP Rocky might represent aspirations or ideals you hold regarding success and charisma. His driving your girlfriend's car could suggest a feeling of vulnerability or concern about your relationship, possibly indicating that you worry about outside influences affecting your connection with her.

Overall, this dream might be prompting you to reflect on your relationships and any conflicts you may be avoiding. It could be beneficial to consider how you can foster communication and understanding with those around you, especially in your romantic relationship. Engaging in open discussions may help you navigate any underlying tensions and strengthen your connections.
