To dream of the brook is the symbolism of your life how it is going through and how you are coping with it. If the brook is clean, it shows that you are able to control your life. If the brook is muddy, dirty or is going too fast, you should slow down and live the life not so fast. If the brook is overflowing, beware of the fact that you are too tired and feel that you have too much to cope with.
