The Big Dictionary of Dreams

by Martha Clarke
To use a colander in a dream reveals the arrival of lawsuits and legal problems because of material issues.

If the holes are tight these issues will be favorable to you; but if, on the contrary, they are wide you will end up losing everything you had won. Seeing other people using a strainer means that, in real life, they do not accept you as you are and that this attitude will make you suffer.
