Dreams often use familiar faces and settings to convey deeper emotions or unresolved feelings from the past. In your dream, your former classmate and the scenario of trying to save her from bullies may symbolize a desire to protect or defend something vulnerable within yourself or in your life.

The fact that you haven't had any significant interactions with her in years suggests that your mind might be revisiting that time in your life, perhaps reflecting on themes of friendship, safety, or camaraderie. This dream could indicate that you are processing feelings related to past experiences or relationships, even if they weren't particularly strong.

Additionally, the act of saving her could represent a desire to stand up against challenges or adversities in your current life. It may also suggest that you are feeling protective over someone or something important to you at this time.

Consider reflecting on any current situations where you might feel a need to advocate for yourself or others, or any unresolved feelings from your past that might be resurfacing. Dreams often encourage us to explore these themes for personal growth and understanding.
