Drinking Abundant Sweet Water
Scholars have interpreted that drinking abundant sweet water may signify a long life and pleasant living. If the dreamer drinks from seawater, they might acquire wealth from a ruler. Drinking from a river suggests gaining wealth from a man whose status among men is like that river's status among rivers. If one draws water from a well and drinks it, they might obtain wealth through cunning and trickery.
