Dreams often reflect our subconscious thoughts and feelings. In your dream, the blue locker represents a space that holds secrets or personal belongings, possibly symbolizing trust and intimacy in your relationship with your husband. The presence of the jewelry, particularly the incomplete pair of earrings, suggests feelings of incompleteness or loss in your relationship, perhaps indicating a fear of infidelity or betrayal.

Seeing your husband's locker filled with women's jewelry might point to insecurities you have regarding your marriage or concerns about your husband's fidelity. The specific association with a woman you know, especially one with a past of infidelity, could indicate that you are processing your feelings about trust, loyalty, and betrayal.

Your reaction of confronting the woman in your dream might symbolize your desire to take control of your feelings and protect your relationship. It could also reflect unresolved feelings about past betrayals or your brother's ex-wife's actions.

Overall, this dream may be urging you to communicate openly with your husband about any insecurities or concerns you have. Consider reflecting on your feelings about trust and fidelity in your relationship, and if needed, seek a conversation to clarify any uncertainties.
