Enema
Scholars suggest that an enema in a dream may indicate self-reflection regarding a matter that will benefit one's religion if it's due to an illness. If it's without illness, it might signify retracting a promise, a vow, spoken words, or a given gift, and could also represent intense anger. It has been said that applying pleasant oil points to good praise, while foul-smelling oil indicates bad praise, and oil in general may signify sorrow.
