Gravy is sometimes taken as a negative symbol, from my understanding. Both Gustavus Miller and the New Family dreambook do coincidentally have the same perspective as the Psychological dreambook! The first author took spoiled gravy as a warning for the dreamer's lack of honesty, and using gravy for a dish was seen as a prediction that the dreamer would frame others and possibly get away with it. I think an author also predicted that dipping foods in gravy means guilt from some troubles. There might be another version of Miller's dreambook that claims gravy is a romantic symbol; or separation.
