Recurring dreams can often reflect unresolved emotions or conflicts in our waking life. In your case, the presence of a man you don't recognize might symbolize aspects of desire, curiosity, or even a longing for emotional connection that you feel is lacking. The flirty and sexual nature of your conversations could indicate a desire for intimacy or a way of exploring your feelings about your relationship.

Your husband's previous infidelity seems to play a significant role in these dreams, suggesting that there may be lingering feelings of hurt, betrayal, or a need for validation. The fact that your husband catches you in the act may symbolize your own feelings of guilt or fear of repeating past patterns. This recurring frustration and resentment might point to your need to address the underlying issues in your relationship, such as trust and communication.

To gain more insight, it may be helpful to reflect on your feelings towards your husband and the status of your relationship. Consider discussing your emotional needs with him in a safe space. Additionally, exploring your feelings about desire and connection can provide clarity and help you navigate your waking life more effectively. Journaling about these dreams and your feelings might also assist you in processing these emotions.
