What does it mean when you dream: Excrement
Useless details or elements which should be cast aside;
Release your attitude, feelings, harmful experience;
Emotional purification; give up things from your past that are no longer useful and which prevent you from moving forward.
All sources pretty well agree that excrement (whether human or animal) in a dream represents money, wealth, profits or tangible value and is a lucky omen pertaining to material gain.
