Very important things are made out of glass. Amongst them are windows that allow sunshine into our homes, drinking glasses, seeing glasses, etc. Glass makes our lives more comfortable and we rarely, if ever give it any thought. Consider the details of your dream and try to figure out how this dream about glass is relevant to you. If glass is shattered in your dream, it could symbolize breaking of both negative and positive things. For example, it could represent the breaking of illusions, denial, and deception. On the more negative side, it could also represent the shattering of dreams or hopes that a person has been holding close to his heart. Old dream interpretation books say that looking through a clear glass is a sign of good luck and through a dirty glass symbolizes domestic difficulties.
