Follow a dream to some law means that in reality you choose the right direction in addressing an issue. To dream of Representatives portends a law that you can not hold back my feelings and saying such things, from which your home will be just in a trance, which will lead to even greater alienation between you.
To dream that you are a member of the legislative institution - meaning that you will not be able to keep composure and be cruel to her family. But you will not achieve real success in their relationships with loved ones.
A law is an instruction or way of working deliberately laid down or fixed so a spiritual law is a universal code which works for all mankind, sometimes more accessible in dreams than in reality. When our emotions are called into question, we can find that an appropriate way of operating is offered in dreams. We work according to unwritten laws that are correct for us. The Law in the guise of a policeman is an aspect of a higher authority there to give guidance. Any aspect of the law appearing in dreams is as much to do with our own code of behaviour in waking life as with ?the law? in the sense of authority. In dreams, our own internal sense of justice tends to take precedence over the laws of society. You might also like to consult the entries for Judge/Judgement, Juror/Jury and Justice.
