To dream that you are a bully means that you are usually the one in control during discussions, events, or social gatherings. It is hard for you to admit that you need someone's assistance. You want everyone to believe that you can handle all of your problems yourself.
To see a bully in your dream indicates that you are not expressing feelings of anger; instead, you are keeping these emotions bottled up inside. The bully may represent a dark side of your personality that you are trying to ignore.
