Furnace – The furnace represents heat, change, and purification. If you dream about a furnace it is very important to focus on everything else in the dream. If you dream about walking into a furnace, whether it is burning or not, it means that you are about to enter a purification state or state of change in your life and that you should be ready for many unpleasant, yet worthwhile, experiences. If you dream about anything important in your life being burned or put into a furnace, a wedding ring, a child, a birth certificate etc., it is indicative of these things happening to that symbolic aspect of your life. The furnace is a very positive omen.
