When we dream of water it usually conveys the emotional state of the mind. Water symbolizes cleansing and purity. To dream of waterfalls is a great omen.
This represents new beginnings as the old is washed out.
If you see waterfalls in your dreams, ask yourself these questions:
Is the waterfall a small one or a large one? How are you perceiving your obstacles? Is the waterfall in a dark jungle or a beautiful beach?
