Dreaming about this interesting and amusing animal may have several different and opposing interpretations. Therefore, it is very important that you pay attention to the details and the emotional tone of the dream.
A donkey may represent humility, honor, and “royalty” in disguise. On the opposite end of things, it may symbolize stubbornness and an unyielding personality. Also, it may represent a person who has many burdens and carries a “heavy load.” Either way, the individual symbolized by the donkey has redeeming qualities which include ruggedness, endurance, and loyalty.
