Dreaming of being trapped in an old mansion can symbolize feelings of confinement or being overwhelmed by your surroundings in your waking life. The mansion itself may represent your mind or your life circumstances, with its many rooms symbolizing different aspects of your thoughts or emotions.

The feeling of being kept against your will suggests a struggle with control or autonomy. This might reflect a situation where you feel restricted, whether in a relationship, job, or personal situation. The encounter with the maid, who represents assistance or guidance, indicates that you are seeking help to navigate these feelings or find a solution to your predicament.

Escaping through a secret route symbolizes finding a unique or unexpected solution to your challenges. It suggests resourcefulness and the realization that there are alternatives available to you, even if they are not immediately visible.

In summary, this dream may be encouraging you to explore your feelings of confinement and seek help from others to find your way out of challenging situations. Consider what aspects of your life currently feel restrictive and think about seeking support or looking for alternative paths to regain your sense of freedom.
