(Coat of mail; Shield) An armor in a dream means protection and defence.
It also means fasting.
If weapons are mixed with the armor or shield in one’s dream, it means that one’s enemies cannot reach him or cause harm to him.
If one sees his armor laying down at his reach in his shop or place of business while dealing with his customers in a dream, it means that such a merchant is untruthful and he uses claims of honesty as a shield.
