Water Dancers

I was going along to a dance class, and discovered that there was a performance going on. It was outside, and there was a kind of man-made water fall (not sure what you call these: they are like steps, with water flowing down them). There were dancers moving in the water itself, this looked quite difficult, but they seemed to be really enjoying it.

What does this mean?

Dance: To dream of dance is a sign that money is coming to you, or that a cherished plan will succeed. To watch dancing signifies that you will hear of a friend’s good fortune
Water: Clear water is good
