Oil
Oil in a dream also represents the light of the heart, spiritual growth, a growing insight, or it may denote birth control, murders, assassinations, or braking someone's bones. Oil in a dream also denotes a broker. If good oil turns putrid or stale in a dream, it means revoking one's covenant, while if a putrid or a stale oil turns good in a dream, it means growing awareness, certitude and adopting a good standard in dealing with other.
