Noise – Dreaming of hearing a lot of noise is a sign of distraction, and oftentimes of frustration at communication. If you have been dreaming about background noise keeping you from concentrating, from hearing another person speak, or from making yourself heard, this is a sign that you feel this same breakdown in communication in your waking life, especially with the particular person with whom you are speaking in your dream when background noise becomes a problem. It is also possible that there is simply a lot of noise going on while you are sleeping, and your brain is assimilating it into your dream.
