If you dreamed that a policeman is trying to arrest you for an action you did not commit, then in real life you will be able to cope with a competitor. If you realize that the arrest is legal, then in your life the black bar will begin soon. To see a police patrol in a dream means that you are threatened with unpleasant changes in business. If in a dream you see and call a policeman, but he does not respond, then in real life you will experience a strong disappointment when those whom you considered your friends will not give you a helping hand.
