Bulls dreams represents an aspect of your personality that is stubborn or headstrong. You or someone else that is obstinate. An unyielding desire to have what you want and have your way.
A bull can be a sign that you are dealing with powerful instinctual urges like lust, sexual desire, or anger. A personality trait that is “bullheaded.” You may need to learn to compromise or practice restraint in a situation.
To dream of a black bull may reflect your fear of someone who is too stubborn to reason with. Feeling that an aggressive person is dangerously unyielding in an excessive manner. Fear of being unable to control your own powerful addictions or urges. A aggressive ignorant person who will never accept you controlling them. Fear of a person or situation that you can’t easily assert yourself over.
Example: A man dreamed of an angry bull inside his house ramming his door to get outside. In real life he was attempting to endure a long cycle of sexual abstinence that was very difficult to stick with. The bull may have reflected his powerful sexual desire that was difficult to control as his urges became too strong.
