This dream may symbolize a desire for recognition and acceptance from those in positions of power and authority, represented by Buckingham Palace and the Queen. The marriage to a distant relative could represent a union with a part of yourself that you have been distant from or disconnected from. The Queen’s insistence on you choosing a wedding ring may suggest a need for validation and approval from others. The disappearance of your engagement ring could symbolize a fear of losing your individual identity in this union. The treasure hunt and wild goose chase may represent the challenges and obstacles you must overcome in order to find and maintain a sense of self within this marriage. This dream may be urging you to reflect on your own desires and needs, rather than seeking validation from others. It may also be a reminder to stay true to yourself and not lose yourself in the pursuit of external validation.
