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.
Additionally, if you are dreaming of a specific body region, or part, consider your health status.
