Dreaming of an encounter—be it a kiss, an argument, or a reunion—with an ex-significant other usually hints at unresolved or rekindled feelings surfacing because of someone or something in your current life. This dream serves as an emotional radar, cautioning you to recognize and correct any familiar habits in your existing relationship. It could be nudging you to apply lessons from your past liaison to your current one. On the flip side, the dream could also be a stroll down memory lane, reminding you of the good times and the love you once shared. Importantly, dreams of reuniting with an ex don't always echo reality and may simply be evoked by changes in your present relationship.
