What does it mean when your ex appears in a dream?

Understanding Dreams of an Ex

One possible explanation for dreaming about your ex is that you haven't completely moved on from that relationship. If lingering emotions remain, your subconscious mind may conjure up images of your ex during sleep, as dreams often mirror our real-life experiences. It's important to note, however, that the feelings you have toward your ex in reality don't necessarily imply romantic sentiments.
