I had a dream about having a very long role of fickle matter (feace) get pooped out of my anus and when I finished pooping it in an open space, I felt a sense of relief.
Dreams about bodily functions, particularly those involving elimination, often relate to themes of release and relief from emotional or psychological burdens. In your dream, the act of pooping out a long roll of "fickle matter" could symbolize the release of something that has been weighing on you—perhaps unresolved feelings, stress, or situations that you have found difficult to manage.
The fact that the material was described as "fickle" might suggest that this burden or feeling is unstable or inconsistent, perhaps reflecting a situation in your life that feels unpredictable or hard to control. The sensation of relief once you finished could indicate that you're subconsciously processing these feelings and achieving a sense of liberation from them.
Overall, this dream might suggest that you're coming to terms with something in your life that has been troubling you, and you're beginning to find a sense of relief or clarity, even if the situation or feelings involved are complex and variable. It can be seen as a positive sign of emotional healing and the importance of tackling issues that have been lingering in your mind.
