This dream may symbolize conflicting emotions and desires within the dreamer. The cousin represents a forbidden or taboo love interest, as marrying a cousin is generally frowned upon in many cultures. The dreamer’s hesitation and discomfort with the idea of changing their surname to their cousin’s may suggest inner turmoil and a sense of going against societal norms. The presence of the cousin’s wife may represent the dreamer’s guilt or fear of causing harm or breaking up a family. The wife’s declaration of love for her husband may symbolize the dreamer’s own feelings of love and loyalty towards someone who is already taken. This dream may be a reflection of the dreamer’s inner struggle with their own desires and the consequences that may come with pursuing them. It may also serve as a reminder to consider the impact of one’s actions on others before making a decision.
