Dreams about people we have feelings for can often reflect our emotions and anxieties regarding those relationships. In your dream, the girl you have mutual feelings for symbolizes your desire for connection and possibly your fear of rejection or misunderstanding.

Throwing the green apple might represent a moment of frustration or disappointment, possibly reflecting your concerns about how your feelings might be perceived. The apple itself can symbolize knowledge or temptation, and throwing it could suggest a desire to reject or push away those feelings when faced with uncertainty.

The girl chasing after you could signify her willingness to understand you better, indicating that there may be hope for communication between you two. Her actions might reflect your subconscious wish for her to pursue you and clarify any misunderstandings.

Overall, this dream seems to highlight your feelings of vulnerability and the importance of communication in your relationship. It may be beneficial to confront your feelings directly in waking life, whether that means discussing them with her or reflecting on what you truly want from the relationship.
