Islamic Interpretation of Dreams (Ibn-i Sirin):
(Dig up a grave; Unearth) Exhuming the body of a deceased person and finding him alive in his grave in a dream means pursuing his tradition, knowledge, wisdom, trade or practices.
It also means acquiring lawful money.
Ifone finds him dead in his grave, then there is no benefit in his striving.
A grave robber or a body snatcher in a dream represents a deliberate and a premeditated scheme to unravel a mystery, or forming an expedition to search for a hidden treasure. Digging the grave of a renowned scholar in a dream means studying his school of thought and the restoration of his studies, life, traditions and prominence.
