Dreaming about your body generally suggests that you are dreaming about your personal identity.
Who we are is wrapped around what we look like. Our self-esteem and self-worth are too frequently dependent on our physical appearance. This dream may be pointing out some of the difficulties or pleasures in daily life that are the result of self-identity and based on attachment to our physical bodies.
The body in general is the symbol of self, and the details in the dream will lead you to further interpretation.
Additionally, if you are dreaming of a specific body region, or part, consider your health status.
