To dream that you see the heron could mean that you feel you are doing something you shouldnt do. You feel that whatever you are doing you have no passion for it and not enjoying while doing it, therefore you dream of heron. The heron in dreams could also show that you do not put the whole dedication and do not put enough of the effort while doing the job or while being in some relationships. In some cases the heron could indicate your desire to be independent from others and receive more freedom.
