To dream of a criminal represents an aspect of your personality that's aware of it's own dishonesty. You or someone else that knows what they are doing is wrong. Feelings about bad influences in your life. Too much lying, cheating, or breaking the rules in some area of your life. Perhaps, there is someone in your life that you find of questionable character?
Negatively, a criminal may reflect your awareness of your own dishonest behavior or attempts to take a risky "short cut" that could hurt you in the long term.
