Water symbolizes the emotional part of our unconscious. So to dream of a flood indicates that an emotion that is too intense has become too much for you, especially if the current takes you and you are unable to stop it. You must try to dominate this feeling or find a means of expression or relief, such as art or relaxation, that allows you to bring it out without emotional explosions. In this way, the flood will become illumination and inspiration. If you don't watch them, your emotions could ruin more than one project. You must not forget of course the nourishing effect of water (such as what happens in a baptism). In this way, the dream could represent the start of a new stage of life. (See water or drowning ) The story of Noah's ark and other similar ones represent the purge to obtain something better. After a flood, all the old has been destroyed. It is the moment to start anew.
