Lots of water can mean you’re over your head or in lots of financial trouble. It could also symbolise stress or the feeling of having LOTS of big responsibilities.
(Betting; Gambling) Casting lots in a dream or betting means adversities, rebukes, reprimands or exaggeration. If one wins a bet in a dream, it means that he will overcome his opponent. If one loses the bet to his counterpart in the dream, it means that he may suffer from a life imprisonment. (Also see Gambling)
