Dreams containing faeces may be odd but they are not uncommon. Faeces represent those things that you no longer need, things that are currently rubbish or waste and need to be discarded. This dream may represent healthy psychological progress. It may indicate that you are cleansing yourself of unnecessary and possibly hurtful attitudes, ideas, and emotions. At times, and depending on the details of the dream, faeces could represent a contaminated area of your life, mind, or spirit. Look at the details and consider if the image of faeces is in regard to something that you have been trying to clean or if it brings up stress provoking thoughts, confusion, and difficult and unresolved areas of your life. In some cultures people believe that if you are dreaming about faeces you will soon prosper financially.
