A waterfall is a positive dream symbol that suggests a cleansing of negative emotions or psychological issues. Just a simple visualization or a daydream of standing in a waterfall makes a person feel energized and refreshed.
If the waterfall in your dream is overwhelming or too powerful for you to enjoy, it may represent emotional energy and unconscious drives that are very difficult to effectively cope with on the conscious level. See also: Water
