A furnace is an enclosed structure in which heat is produced.

Positive:  Dreaming of a furnace could represent God’s protection power over your life, that no matter what happens, He is there to protect you. Dreaming of a furnace could represent having faith.

Negative: In a dream, a furnace could represent Hell. It could also represent eternal death and suffering. Furnace dreams can often indicate a warning dream from God.

(Daniel 3:5; Matthew 13:42; Revelation 1:15).
