Using a broom to sweep indicates a strong desire to clean all non-essentials out of your life.

If the broom is new, it implies good news and/or success.

If the broom is old and dirty, however, making the necessary changes in your life is going to be more difficult and take longer than you think.

Dreaming of the plant broom indicates that you are feeling bitter about something in your life, or that you feel that your life is barren and joyless.

If the plant is flowering, however, there is a chance for a new start.
