Drinking Water
Scholars have said that drinking water in an unfamiliar place or from an unknown vessel may indicate the depletion of a part of the dreamer's life or livelihood. Clear water in a vessel may symbolize accumulated lawful wealth. It has also been said that a large jar (khabiya) may signify a good woman, and drinking from it could mean acquiring wealth from her.
