Dreaming of falling off a cliff, especially in the context of your relationship, can symbolize feelings of insecurity or fear of losing something important to you. The cliff often represents a significant change or a risky situation, while the act of falling may reflect feelings of helplessness or anxiety about your relationship's stability.

Your fear of losing your girlfriend in the dream suggests that you may have concerns about the future of your relationship or a fear of abandonment. It could also indicate a need for reassurance in your connection with her.

Consider reflecting on your current feelings and any challenges you may be facing together. Open communication with your girlfriend about your emotions might help alleviate some of your fears and strengthen your bond. It’s essential to address any underlying anxieties to ensure a healthy relationship dynamic.
