Cowboy 
To see or dream that you are a cowboy represents manliness, severity, and robustness. You are capable of managing your basic primal desires as well as your intuition.
Rodeo
To dream you are in a rodeo suggests a need to contain, bind, and conquer your raw passion.
Mechanical Bull
To ride a mechanical bull in dream is a symbol of your sex life. You may be craving sex, but the sex available to you has become a pattern of dull and routine motion.
Alternatively, you may be afraid to unleash your sexual urges and searching for a way to express them. Riding the mechanical bull is a traditional act of exhibitionism, which may substitute in a dream for a sexual fantasy if your feelings have been repressed.
