Dreams involving past relationships can evoke a range of emotions and may reflect your current feelings or unresolved issues. Seeing your ex-boyfriend alongside his ex-wife in your dream suggests themes of nostalgia, comparison, or even closure.
The surprise you felt in the dream might indicate that you are processing feelings related to your past relationship, perhaps questioning how far you've come since then or considering the impact of past choices. His silent presence could symbolize feelings of unresolved issues or unexpressed emotions between you and him.
Consider reflecting on your current emotional state regarding relationships and whether there are aspects of your past that you still need to confront or let go of. This dream may be an invitation to explore those feelings and find a sense of closure or understanding.
