Worms are associated with something that is unpleasant and as a living thing beneath the soil, can represent feelings of being unworthy. Yet, because worms re-stabilize the soil, bringing it nourishment, dreaming of worms can also symbolize a type of rebirth. Caterpillars have a similar meaning since they transform into butterflies. To dream of maggots can represent how you know a situation has reached a point of decay and needs to transform. These types of creatures are capturing the feelings of insecurity you may feel. The initial feeling of displeasure associated with insignificance usually manifests when you are moving toward self-acceptance. Now that your feelings are out in the open - you can transform.
