To dream that you are cashing a check represents cashing in a favor, collecting on a debt or promise, or an “I-O-U.” To dream that you are cashing a bad check suggests a promise that was never meant to be kept, or a favor that was never meant to be redeemed. The promise or favor can be financial, but it doesn’t necessarily have to be – it could also be emotional, spiritual, or some other form of physical trade.
