Deceiving someone in your dream and apologizing is a sign of repentance after a sin and regret after a mistake. If the person who sees such a dream knows the person he cheated on in the dream, he commits a crime against him in real life and regrets it as a result. If you do not know the person you cheated with, it can be interpreted as a sin and then repentance.
To see in a dream that you do not cheat on your spouse, fiancee or lover but only desires it indicates that you are inclined to commit some sins. This dream indicates that you do not do some wrong things because you are afraid of sins or people's words, but you can commit these mistakes if you get the opportunity.
