Eating dill in a dream is usually interpreted as a sign of prosperity, fertility and spiritual protection. Dill is known for bringing about good fortune and happiness when eaten.
This simple plant has had many strange interpretations throughout history. It was believed that dreaming about eating dill tempered the effects of snake venom, that it increased fertility in pregnant women, that it could ward off nightmares and could also be used in spells to avert the dangerous attention of ghosts who wanted children or sexual attentions from human males.
Also, the idea of smelling the leaves when shy and uncomfortable might bring some clarity to this topic. Dill is often associated with family history, decision making and improving those attributes. If your dream has a keen association with this herb, such as watching your mother pick herbs next to one growing in her garden then it could suggest feelings of protection and love from home.
