Tail in dream meaning

To see only the tail of an animal in your dream signifies annoyances and complications in a situation where pleasure was expected. If the tail is wagging, then it symbolizes excitement, thrills, and joy. If the tail is between the legs, then it represents fear and humiliation. Alternatively, the dream represents balance. Or it may  be a pun on “being tailed” as in being followed or chased.

To dream that you have grown a tail represents an aspect of the past that still lingers with you.
