To dream that you are a Jedi indicates that you are in tune with your spiritual powers. You need to believe in mind over matter. Or you need to trust in your own metal powers.
To see a Jedi in your dream symbolises the challenges in your life and the difficult decisions you are confronted with. Alternatively, it represents your quest for order and peace.
Dreaming that a Jedi is fighting with a Sidth represents conflict between good and evil. Perhaps you are torn with doing the right thing. You are struggling to not let negative emotions take over your actions.
