Referee 
To dream of a referee indicates an inner struggle between holding on to your ideas and values and giving in to the judgements and recommendations of others.
Judge
To dream of a judge may be providing snippets of wisdom to help you make sound decisions. On a more direct note, this dream may signify that misunderstandings can be properly resolved in a court of law.
Arbiter
If you're an arbiter in a dream, it is warning you that you are above the rules or going out of control. To see or work with an arbiter in your dream, it means that you are currently going through a difficult time, or that you wish for a resolution to some conflict or problem in your life.
