In Greek mythology, Cerberus is a fierce guardian in the form of a multi-headed dog who protects the entrance to the underworld. Your dream suggests that you are in a situation in which you are required to protect something or someone. You may feel that you are being forced to be something other than what you want to be. Perhaps you would rather be gentle and welcoming rather than perceived as vicious and threatening.
