Dreams where you cheat on your partner can make people feel guilty and confused. Many wonder, "If I'm happy in my relationship, why is my mind wandering to being with others?" This is an understandable question, but the reality is a bit more complex than it seems.
Dreaming about cheating doesn't mean that you're going to cheat or that you want to (via Healthline). There are a few reasons why this dream may have popped up. Sometimes cheating dreams occur because of something you feel that you're lacking in your current relationship. If you're feeling emotionally or sexually deprived or distant from your partner, it may manifest this way in your dreams. If you have cheated in the past, this may indicate that you have residual guilt. On the flip side, if you have been cheated on in the past, a dream that you're cheating may mean that you're afraid it will happen again.
It's also highly plausible that this dream has nothing to do with your partner or your love life, at all (via Bustle). It's common for dreams to actually be metaphors instead of directly relating to your life. (You know, like how the teeth-falling-out dream isn't actually a warning about your oral hygiene.) Dreams about cheating with your ex may have nothing to do with your ex or your current partner. Rather, they might denote that you're having feelings of guilt or that you are betraying yourself.
