Your dream is rich with symbolism and themes that reflect your current emotional state and experiences. Let's break it down:

1. Snowy Town and Family: The snowy town could symbolize a period of coldness or isolation in your life, perhaps reflecting feelings of uncertainty or a need for protection. Your family represents your support system, emphasizing the importance of safety and security in your life.
2. The Fight: The prolonged battle suggests that you may be facing challenges or conflicts in your waking life. Your role in defending your family indicates a strong desire to protect those you care about, showcasing your sense of responsibility and loyalty. The backup from special forces symbolizes unexpected support or help that may come your way during tough times.
3. Graduation Scene: Graduation often signifies a transition or a new chapter in life. Your feelings of embarrassment about your attire could indicate insecurities or fears about not being prepared for upcoming changes or judgments from others. The contrast between your casual outfit and the formal attire of your peers might reflect feelings of inadequacy or a fear of not measuring up.
4. Interaction with Friends: The presence of your friends and the nostalgic conversation highlights the importance of camaraderie and the longing for close relationships. It may suggest that you miss those connections and feel a desire to return to simpler times, or perhaps you're yearning for that support as you navigate changes in your life.

Overall, this dream might be urging you to confront and prepare for challenges while reminding you of the importance of community and support from friends and family. It may also be pointing to some anxieties about your current path or upcoming transitions. Consider reflecting on what areas of your life feel overwhelming and how you can seek support from those close to you.
