Like the Cup, a glass can be associated with the things you hold to be important. As a receptacle for liquid refreshments, it is associated with feelings or the intuitive flow of information. Dreaming of either can portray holding or trying to capture these things in an effort to gain insight about sustenance. A broken glass portrays a sense of pain or fear associated with feelings. Glass that acts as a barrier, such as a window, can symbolize the idea of blocking intimacy. If this type of glass breaks, you are trying to achieve a sense of intimacy with someone.
