Dream about becoming a leader is a clue for your need to fulfill your goals. You need to be more positive in your thinking. You are blind to something that everyone else is clearly seeing. It is a harbinger for your need to exhibit some of good qualities in your life. You need to see things in a more positive light.
Becoming a leader is a metaphor for your attitudes of courage and violence/passivity
There is something that you need to ignite and rekindle in your life. Suspicions are lurking around you and your activities. It points at the rewards you get when you set your mind to pursue your goals. You are refusing to acknowledging some truth or issue that is right in front on you.
