To dream that you are being saved from falling over a waterfall indicates that you are letting distractions to keep you from moving forward in your life.
You are wasting your energy by dwelling on minor things rather than being willing to confront the significant shift that would propel your life forward.
Dreaming about saving someone before they go over a waterfall indicates that you feel as if the world around you is moving too quickly and that you want to take control.
This may manifest itself in your dealings with coworkers, friends, family, and acquaintances as being domineering or aggressive.
