Chrome is a metallic material that is reflective, corrosion resistant, and used for several different things. Chrome in a dream could represent a cold or hardened heart.
Positive: If you see something covered in chrome plating, it could represent that that particular thing is well preserved and cannot be easily destroyed.
Negative: Dreaming of a heart covered in chrome could represent that it is cold and hardened.
(Matthew 24:12-13; Zechariah 7:12).
