A vat seen in a dream is an ill omen but must also be taken in context of the entire dream and correlated. This can foretell sorrow, grief, cruel friends, an unfaithful lover, etc..

Islamic Dream Interpretation

by Ibn Seerin
(Tank, Tanning drum, Tannery, Woman) A vat in a dream holds the same interpretation as a tannery, except if a tannery represents an independent woman in a dream, then a vat will represent an inhibited woman.

A vat in a dream also represents a bathhouse, death by drowning, or dying under a collapsing structure.
