Islamic Interpretation of Dreams (Ibn-i Sirin):

(Burnishing; Shining) A wood finisher polishing a piece offurniture in a dream represents a minister, an administrator, or a statesman who deals with the high and the low.

Seeing a polisher in a dream also means befriending a righteous man who points out one’s pitfalls and helps him to remove his ills and to correct himself.
