The sad news of interest in your face.
To dream of infidelity (either by you or someone else), forewarns of your actions with the opposite sex or you will suffer dire consequences. You are harboring guilt over a sexual relationship. Alternatively, you are feeling unsatisfied with your current relationship. You want to seek a more exotic sex life. Or you are feeling emotionally confined and need an outlet for your feelings.

If you dream of cheating in any manner, either by you, or by your loved one, then this is a direct warning for you to be more circumspect about your actions to and with the opposite sex. It is warning you that if you do not, you will suffer the consequences. If you are the cheater in your dream, you may have a guilty conscious about cheating that has nothing to do with love.
