To dream of a lilac flowers represents feelings about how beautiful it is to notice never fearing a sense of accomplishment in something that isn’t dependent on anything else. A sense of accomplishment in something that nobody else wants to do that always cares about your feelings. Feeling good noticing yourself successful from being self taught. Feeling good about your children having grown up to be independent never needing you for anything.
Example: A woman dreamed of seeing someone take lilac flowers out of a bouquet meant for her. In waking life she was having issues with her company failing and a need for perfectionism. The lilac flowers being taken by someone else may have reflected her feelings about a habit, problem, or other person not allowing her to enjoy herself feeling accomplished without dependence on others.
