Defecation

 

(biological), the discharge from the digestive tract of food remnants unassimilated by the body. In mammals and man, the term refers to the evacuation of the fecal mass from the large intestine. In defecation, the sphincters that close the rectum are reflexively relaxed, and the feces are discharged by peristaltic movements of the large intestine and the rectum. The center for the defecation reflex is in the lumbar region of the spinal cord. Voluntary influences that excite or inhibit defecation come from the brain.

(dreams)
Dreams that include excretory functions usually represent cleansing and emotional release. Look at all of the details of the dream in order to obtain meaning. Ask yourself which emotions you may be releasing: anxiety, anger, mockery, annoyance, etc. Some very old folklore interpretations suggest that dreaming of feces is a good omen that suggests a financial gain.
