Dreams about bathrooms often symbolize the need for release or cleansing in some aspect of your life. In your dream, the dirty stalls and the unpleasant situation you encountered may represent feelings of being overwhelmed or disgusted by certain situations or emotions that you cannot escape. The feces could symbolize negativity, shame, or something that you find repulsive in your waking life.
The act of rushing to use the bathroom may indicate a sense of urgency to address an issue, but finding it in such a filthy state suggests that you are confronted with challenges that you find difficult to manage. The necrosis on your face at the end of the dream might symbolize that unresolved issues are starting to take a toll on your well-being or self-image.
This dream may be urging you to confront problems or emotions that you have been avoiding. It could be beneficial to reflect on areas of your life where you feel overwhelmed or burdened and consider how you can begin to address these feelings. Taking steps to cleanse yourself of negativity—whether through self-care, talking to someone, or finding healthier coping mechanisms—could lead to a more positive outcome.
