The significance of this dream varies according to the circumstances of the dreamer. If you are in business or in a job, it signifies that hard, or harder, work will be necessary to attain what you want. If you are a working professional, it indicates that a further course of study or the acquisition of higher qualifications would be beneficial to your aims. If you don't fit either of these categories, then the key to the meaning of the dream lies in the effort involved in the action; if the soil was soft and/or the digging easy, you are likely in for a happy period of easy living; if the digging was hard and slow going, you may have to struggle for a while yet.
