Calomel

To dream of calomel shows some person is seeking to deceive and injure you through the unconscious abetting of friends. For a young woman to dream of taking it, foretells that she will be victimized through the artful designing of persons whom she trusts. If it is applied externally, she will close her eyes to deceit in order to enjoy a short season of pleasure.
