A bull is an energetic, heavy and powerful animal. Therefore, if it appears in your dream, it may signify your physical characteristics or your traits of character. Physically, the bull symbolizes an aggressive, strong, powerful person, full of vitality and stamina and endowed with endurance. The most pregnant traits of character the bull appearing in your dream stands for are optimism, enthusiasm, confidence and other related positive feelings.
On the other hand, the bull may stand for clumsiness when it comes to handling delicate things or problems. Instead, if a bull appears in your dream, this means that you head on towards, venture in risky new situations without thinking twice. This may be a wrong way to deal with things, as a bit of caution is still needed, but the optimism which characterizes the bull will help you become victorious in all situations.
The bull also stands for masculinity and virility. Consequently, if the animal appears in a man's dream it means that he is virile and sexually potent, and when the animal appears in a woman's dream it represents lust and sexual desire.
The buffalo may also be associated with your 'animal', untamed side, with your instincts and primitive desires, such as sexual desires and fantasies. Linked with the energy of the heavy animal, this 'wild', irrational tendencies attempt to come out to light and rule your life. Especially, if in the dream you are avoiding or running from an enraged bull, this means that your inmost instincts are going to dominate your whole behavior and life if you do not resort to reason and intellect as soon as possible to tame the 'beast' inside.
But if in your dream you can catch the bull by the horns and tame the animal, then you will succeed to overcome the 'wild' instincts and create a balance between primitive desires and intellect and morality.
