What does dreaming about oil mean in the Bible?

Oil in Scripture marks anointing and gladness — "You anoint my head with oil" — and readiness: the wise virgins kept oil in their lamps for the bridegroom's arrival. The elders anoint the sick with oil in prayer. An oil dream may speak of being set apart, kept ready, or brought toward healing. In the SoulGuide Dream Guide, oil is filed under objects — one of 54 symbols in the guide — and is answered with 3 King James Version passages quoted in full: Psalms 23:5, Matthew 25:4, James 5:14. Each passage below carries a short note explaining why it applies to oil, so the entry can be read on its own without the rest of the guide.

“Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.”

“But the wise took oil in their vessels with their lamps.”

“Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:”
