1. Use extreme caution toward loved ones; reassess motives carefully.
2. A feeling that someone harbors resentment or hostility.
3. Feelings that a harsh situation will beneﬁt no one without careful consideration.New American Dream Dictionary | Joan Seaman - Tom Philbin
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.Ten Thousand Dream Interpretation | Gustavus Hindman Miller
