A large fountain represents feelings of love and generosity; this symbolizes feelings coming not just from one single source but many sources.
If you want to highlight your personal history that led to your current successes, and you dream about going to the fountain for water to drink, this could mean that it is time for you to re-evaluate the past and realize what led to where you are now. The dream may be telling you that you must continue drinking from the fountain of life.
If a person is trying not to waste their time in vain pursuits, they might have a dream with a dry fountain at night as they lie down in bed.
