Gum – Gum is a symbol of futility and empty effort. If you dream of chewing gum, this indicates effort you are putting with no results, and without the expectation of results. Because the mouth is such a powerful symbol of communication, your dream about chewing gum may show frustration in being unable to communicate, especially with one particular person in your life. To dream that you are chewing gum and cannot speak because your mouth is full shows that your thoughts are too full and complex for you to express them completely, or that your relationship with the person you are trying to talk to is stifling you.
