Dream meaning » sponge
To see or use a sponge in your dream suggests that you are receptive and are able to easily absorb new knowledge and information. The dream may also be a metaphor that you are “sponging off someone” or that someone is “sponging” off you. Perhaps you are becoming too dependent and need to find your own path.

The meaning of this dream varies according to the action, but its omen is generally good. If you washed with the sponge, it forecasts satisfying recognition for work well done; if you squeezed water out of it, you can expect an increase in your income; but if you tried to squeeze it and found it dry, you are being warned against indulging in any form of gambling at the present time.
The essence of a sponge is its ability to absorb. We use this simple plant life as a metaphor for learning at an aggressive rate, as in soaking something up like a sponge. In a dream, a sponge may indicate a desire or present circumstance in which there is a lot for you to take in. The context in which the sponge appears in the dream should offer some clues about what area of your consciousness is currently expanding.
