Dream have been viewed as connection to the unconscious. They range from normal and fun to overly bizarre. Dream are generally out side of the control of the dreamer,  with the exception of lucid dreaming. Lucid dreaming is being aware that you are dreaming, you have control for the role in the dream, or be able to change the imaginary and experience in the environment.
