Strong or destructive power. Something has to be dug up from deep down. Uncover the foundation and dig for the treasure that is buried deep. Occasionally, this is a dream symbol for something colossal, as in Monster.
To see a grave digger or excavator in the dream means death for the one who sees it provided any of the following happens; he pushes the grave digger away from his place; his animal tramples the grave digger, the grave digger falls on the ground; he himself is in the state of sakraat. But if any of the following happens then he will either lose his job or die; he rolls up his bedding; his turban or topi falls off from his head; his hand gets cut off from his body; his tongue is cut off; he becomes blind.
