When the water well is well constructed, uncovered and full of water, then it becomes a symbol of sincerity, honesty and happiness. If the well is poorly constructed, sealed or the water dries up, or the rope breaks, or the bucket is holed and the water cannot be retained the meaning is totally contrary. If in our dream we fall out the well it is one of the worst omens, unless someone get us out of the well. It symbolizes that we are immerse in the depths of the unconscious, unable to return to the conscious, which is equivalent to desperation, neurosis and madness.
