Anything associated with the mouth usually represents communication. If you are unable to ‘digest,’ process or express something, you may dream of vomiting. The symbol that is vomited or character that is vomiting will shed light on what this may be. For example, if it is a child, then it relates to issues of childhood you may have difficulty 'stomaching.' If you are vomiting a green fluid, it can relate to healing. See Colors.
