Your dream seems to be deeply connected to your emotions surrounding your ex-boyfriend and the feelings of loss and longing that may still linger within you. Here are some interpretations of the key elements in your dream:

1. Seeing Him with Someone Else: This part may reflect your feelings of jealousy or sadness regarding your ex moving on. It’s natural to feel a sense of loss when you see someone you cared for moving on with another person, even if it’s just in a dream.
2. Going to the Restaurant Alone: This could symbolize your desire for independence and self-reflection. It shows that you are trying to enjoy your own company, but it also hints at feelings of loneliness.
3. The Bartender: The girl who was bartending might represent a connection to your past or the social circle related to your ex. Her recognition of your mood indicates an awareness of your emotions, which suggests that you might be seeking comfort and understanding from those around you.
4. Encountering Your Ex: The interaction with him in the dream signifies unresolved feelings. His initial avoidance and then the embrace can symbolize the complexity of your past relationship—how you may still have emotional ties despite the distance.
5. Hand Holding and Intimacy: The physical closeness in the dream speaks to a yearning for connection and intimacy. It shows that there are still feelings of affection and perhaps a desire for reconciliation or closure.
6. The Setting: The parking garage could symbolize a transitional space, indicating that you are in a phase of moving from one emotional state to another. It reflects the uncertainty you may feel about where you stand in terms of your past and your future.

Overall, this dream might be urging you to confront your feelings about your ex, whether it’s seeking closure, healing, or simply acknowledging that you still have unresolved emotions. It’s important to give yourself space to process these feelings and perhaps consider what you truly want moving forward. Engaging in self-care and surrounding yourself with supportive friends or activities might help you navigate through this emotional landscape.
