Interpretation 1 — Theresa Cheung
The furnace is a powerful symbol of creativity as all the fire’s energy is devoted to one specific task.
If you are using fire to forge something, such as a tool, your dream may be hinting that you should use your creativity and passion more in waking life. Have you developed a burning interest in something or someone recently and isn’t it time to pour your energy into making it a reality?
