Bull (wild) dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Klaus Vollmar
The bull / steer and Tiger are always personifications of drives and urges. Running after a bull in a dream means you are in conflict with your drives. You must always confront the bull or the tiger in your dream, because both have something important to say.
The bull is a symbol of masculine (originally feminine) strengths, fertility, and potency. Also indicates that animalistic urges have been mastered.
