Iron usually symbolizes power. In a dream it can signify the part of ourselves that is capable of discipline – an iron will. However, before being tempered by fire (life’s challenges) and made into hard steel, iron requires protecting against corrosion. It is this quality of the development of protection against spiritual ‘corrosion’(eating away) that needs to be dealt with so we can progress.
Psychological / Emotional Perspective:
When we dream of using a clothes iron we are attempting to make ourselves more presentable to the outside world. We may also be trying to ‘smooth things over’.
Everyday Material Aspects:
When the metal iron appears in dreams, it usually represents our strengths and determination. It can also signify the rigidity of our emotions or beliefs. We should consider being more flexible.
