Being deceived by your lover, deceiving your lover

From the interpretation of dreams by Duke Zhou, if you are married or have a regular friend of the opposite sex, but have sex with another man in your dream, or consciously deceive your husband or boyfriend in your dream. Then this means that you are showing signs of cheating on your lover or will soon act in your dream.
Interestingly, if your boyfriend tells you a similar dream, it may mean that his feelings for you are fake, and he may have been confused or suspicious about your relationship.
