Vitriol

If you see vitriol in your dreams, it is a token of some innocent person being censured by you. To throw it on people, shows you will bear malice towards parties who seek to favor you. For a young woman to have a jealous rival throw it in her face, foretells that she will be the innocent object of some person's hatred. This dream for a business man, denotes enemies and much persecution.
