Digging in a dream often represents the process of learning about yourself. You may find yourself digging, or excavating in a dream when you need to understand yourself better in order to move forward toward a goal.
When you are digging in a dream, for example, digging a hole or excavating a mine, you are uncovering parts of yourself that you have been keeping hidden, possibly because they are painful to accept.
To dig something in a dream can be a way of learning to face and to accept these repressed emotions and memories, so that you can deal with them and move on.
Digging into the earth in a dream can be a message that you need to look back at your past if you are to solve a current problem.
An old object, or old bones, that you discover while digging in a dream can represent a buried memory.
