Dreaming of extremely dirty bathrooms can symbolize feelings of vulnerability, discomfort, or a sense of being overwhelmed by emotions or situations in your waking life. Bathrooms often represent a place of release and cleansing, so the dirtiness may indicate that you are struggling to let go of negativity or that you feel stuck in a situation that needs addressing.

The doors that won't lock could suggest feelings of insecurity or a lack of privacy in your personal life. You might be experiencing situations where you feel exposed or unable to protect your boundaries. This could reflect anxieties about being judged or having your personal issues exposed to others.

Overall, this dream may be prompting you to examine areas in your life where you need to find a sense of control, privacy, or cleanliness—both physically and emotionally. Consider what aspects of your life may feel messy or unmanageable and think about ways to restore order and safety.
