Dreams that involve themes of transformation, such as being born as the opposite sex, often reflect inner conflicts regarding identity or a desire for change in your life. Being born into a noble family in a different time and place may symbolize feelings of privilege or societal expectations that you feel pressured by.

The forced marriage to someone you don't get along with could represent feelings of being trapped in your current circumstances or relationships, where you feel you lack control. The attempt to escape signifies a desire for freedom and independence from situations that feel confining.

Hiding in the family mausoleum suggests grappling with past issues or buried emotions that you may not have fully confronted. The imagery of the dead bodies overpowering you can symbolize fears or anxieties that you feel are overwhelming you, particularly those that relate to the past, such as unresolved issues or feelings of vulnerability.

Overall, this dream might be urging you to explore your feelings about identity, relationships, and any aspects of your life that feel oppressive. Consider reflecting on what changes you desire and how you can take steps toward feeling more empowered and free in your current situation.
