Your son can indicate your male side or that you had issues with your father when you were the age of your son in the dream. We each have both male and female aspects to ourselves. Dreams encourage you to restore balance to this energy mix. In fact that is one of the main purposes of your life.
To dream of your son dying asks you to eliminate the negative conditioning you picked up around the age of your son in the dream.
To dream of rescuing your son asks you to rescue a male aspect of yourself that was lost at the age of your son in the dream.
