I had a fight with my current girlfriend and I saw my ex on my dream
Dreams about fighting with someone, especially a romantic partner, often symbolize inner conflicts or unresolved issues that need to be addressed in waking life. Seeing your ex in the dream could represent longing for a past relationship or an unfulfilled desire that you had with your ex. Alternatively, seeing your ex could represent qualities or traits that you wish your current partner possessed.
Overall, this dream may be pointing to an internal struggle that you're facing in your current relationship. It's possible that you're still carrying unresolved feelings about your past relationship or that there are certain qualities you're missing in your current partner. It may be helpful to reflect on your emotions and communication with your current partner to see if there are any underlying issues that need to be addressed.
