If you are having an affair in a dream, you are being asked to get intimately in touch with your male side if you are having an affair with a man, or your female side if the affair is with a woman. Having an affair with a person of the same gender means the same thing. We all have male and female aspects to ourselves which have their own unique traits. For example, compassion, listening, leadership and your philosophy of life work through your female energy. Confidence, belief in yourself, feeling worthy of the space you occupy, career, ambition, sex drive and spiritual healing work through your male energy. The dream may be triggered due to an imbalance which is affecting your ability to develop or move forward in an aspect of your life.
To dream of your partner having an affair is not a prediction or confirmation. It merely means that your dream is trying to get you to work through your feelings for your partner. It can be triggered if you had or considered an affair in this or a previous relationship?
