Islamic Interpretation of Dreams (Ibn-i Sirin):

(Chemical; Hunt; Pipe) Discovering lead as a mineral in one’s dream means prosperity and strength in one’s livelihood.

Forging lead in a dream means becoming competently qualified in one’s craft. Lead in a dream also represents earnings from a despicable source based on passion and wantonness. Lead in a dream also means becoming courageous, or unfailingly speak what’s on one’s mind. Carrying a container of liquid lead in a dream means that one should be careful about his expenses. Melting a bar of lead means a dispute or a prattle.
