To dream of the lily flower represents sensitivity about noticing that a situation or relationship is more special or more beautiful than others.
Negatively, dreaming of may represent situations where you or someone else is putting a positive spin on a bad behavior. Trying to feel good that something bad or wrong is a beautiful thing. A positive attitude about adultery.
Example: A woman dreamed of being given flower by a man. In waking life she was cheating on her husband with a man that didn’t want a serious relationship and wanted to keep the sexual relationship the same. The flower represented how the man she was having an affair with wanted her to feel good about noticing that the adulterous sexual relationship was a special one because the sex was so good.
