Dreams involving feces can often symbolize feelings of shame, embarrassment, or a need to let go of something negative in your life. In your case, seeing your underwear covered in poop, despite not being the source of it, may represent feelings of being judged or feeling dirty over something that is not your fault.

This dream could suggest that you are grappling with a situation where you feel accused or burdened by something external. It may also point to a need to cleanse yourself emotionally or mentally from a situation or relationship that feels toxic.

Consider reflecting on any current situations or relationships that might be causing you distress. It may be helpful to address these feelings directly to find peace and clarity.
