The meaning depends on the details and the action of your dream, but as a general guide, clear, calm water is a favorable omen, while rough or murky water signifies difficulties. A dream of drinking cold water is a sign of good luck, but throwing or spilling it on anyone indicates a need to control your temper. Hot water (unless it is appropriate to the action) portends a season of social and/or business setbacks, but running water predicts lasting happiness. A waterfall in your dream forecasts a happy rise in status and/or an imminent increase in material wealth. Gently flowing water promises contentment and peace of mind.
