Islamic Interpretation
In a dream, mercury signifies a plan or intention that will remain unfinished. Seeing oneself giving mercury to another person or holding it in one’s hand indicates breaking promises. It also points to weakness in religious observance, following personal desires and reasoning, or being deceptive, unfaithful, or treacherous. If one eats mercury in a dream, it means that one of his children will grow up to be someone who does not keep his word.
