Rough Sieve in dreams
A mesh tool that separates fine from coarse — the work of letting through only what is wanted.
How rough changes the reading
Rough texture adds friction — the symbol is real and useable but the surface of the situation has been worn. The dream is rarely critical; it is noting that the work of it has left marks.
The base reading of Sieve
A sieve in a dream is the dream's image of selective filtering. The sieve does not change what is poured into it; it lets through what is small enough and holds back what is not. The dream brings the sieve when you are sorting through a large input — information, advice, options — and the task is to keep only the fine grain. A sieve doing its job cleanly is the dream telling you the filter is working. A sieve clogged or torn is the dream noting that your filtering has stopped functioning and either nothing is getting through, or everything is.
