Id be happy to help assist you in understanding your dream. Often times dreams are symbolic. I take it your trying to seek an answer regarding your husbands faithfulness to you through a dream? Usually we receive what we are not expecting. With the quarter in the dream, it symbolizes gifting, favor and responsibilities. Silver is the color of redemption, "being redeemed" from something in one's life. Since there are 2 quarters, it is showing division or a persona decision being made. A key represents a "key" to something in your life. A tool to help guide you in the right direction. Getting on the bus usually represents the world and where one is going within the world. It is showing this process of your thoughts taking place. The dream is not showing any obvious answer if your husband cheated or not. But it is in the beginning stages, as your thoughts and feelings are coming forth in the dream. This is the decision being made and the two quarters and key. You are indeed on the right path to gaining knowledge that you are seeking. Now my question to you is, have you discussed this with your husband. How did he respond?
