Dreaming of a rotten box can symbolize feelings of decay or unresolved issues in your life. The box often represents something that is meant to contain or protect, such as your emotions, memories, or aspects of your identity. If the box is rotten, it may suggest that there are negative feelings or problems that you need to address, as they could be affecting your overall well-being.

Consider what the box contained and how it relates to your waking life. Are there aspects of your past that you need to confront? Are you holding onto something that is no longer serving you? This dream might be urging you to let go of the old and embrace change for personal growth. Reflect on areas in your life where you may need to clean out the "rotten" parts to make space for new experiences.
