Interpretation 2 — Stearn Robinson - Tom Corbett

The roar of rushing water in your dream is telling you that you are likely to defeat your own purpose by overaggressiveness; try a little gentle persuasion.

If your dream featured the roar of machinery, it is a warning of unsuspected rivalry.

Otherwise, see under Lion, etc., or Animals.
