Dreaming about defecation or excrement can be interpreted in different ways. It could symbolize the release of negative emotions or unwanted aspects of the dreamer's life. It could also represent the need for cleansing or purification from something negative.
The fact that the toilet bowl is filled to the rim with feces could suggest that the dreamer is overwhelmed with unwanted emotions or experiences that they are struggling to handle.
