Clouds are a clear indication of difficulties. However, contrary to what it seems at first glance, this can be considered a good omen. The dream is telling us that, despite setbacks, we can succeed in our projects through effort and perseverance. It also augurs fertility after a long period of barrenness. According to other interpretations, clouds represent our mood. If they are very white and look like cotton, then they denote joy and spirituality. If they are black and sinister, they indicate depression or anger. Clouds also predict rain and, with it, the opportunity to release tension. Many traditions warn that you must clear your "clouds of ignorance" to make way for spiritual enlightenment. Similarly, clouds protected the Greek gods of Olympus. Only your intuition can cross that barrier and reach the higher knowledge.
