Spiritually we need to have access to the characteristics of the unconscious. It will always take effort to uncover such aspects and this is symbolized by digging. Excavating, perhaps in the form of an archaeological or other professional type of digging, would suggest a more structured approach. On a creative level we may have realizations that are hard to access and must be dug out. Excavating objects can also imply that there is 'buried treasure' which belongs to the past. Often when we begin the process of learning about ourselves we need to uncover those parts we have kept hidden, and this is shown in dreams as excavating a hole or digging up an object. If the act of digging is important then we are required to make an effort rather than simply wait for information to come to the surface. Also consult the entry for Mine/Miner.
