(Bolter; Colander; Filter; Separate; Sift; Sort; Strainer) In a dream, a sieve represents knowledge, discerning, honor, rank and discriminating between truth and false.
A sieve in a dream is like a detector of true banknotes from counterfeit, a person who chooses his words, a choosy person of the type of work he does, or a discriminating buyer, a pious person, or it could represent a comb.
If a sieve is given as a collateral, or as a promissory note in a dream, it means that the depositor will flunk his promise, for a sieve does not retain water. (Also see Bolter; Strainer)... Islamic Dream Interpretation
Vision: Looking at a sieve: you have actcd foolishly and the result will be very unpleasant. Make sure that you keep an eye on things.
If you are putting something through a sieve: something you want to do is turning out to be hopeless, and if you proceed you will only be wasting your energy. Using a sieve: somebody is asking you to account for your actions.
Depth Psychology: This is the time to “sift” through things and discard what is useless.
The dream is an admonition to be more critical, especially about what you do, and change your materialistic view of the world.... Dreamers Dictionary
