What is the quality of the earth in your dream? Is it richly fertile or a wasteland? Sandy soil suggests uncertainty; red earth, hard work and toil, and rich, dark soil, satisfaction. Soft soil links with the need for mothering or tactile contact.
Parched or barren ground is, however, a sign of inner conflict or exhaustion, suggesting that you should search your dreamscape for signs of hope. Sand in a dream suggests instability and lack of security, especially if you see it together with the sea.
If the sands are shifting, you may feel uncertain about what you want from life.
If you see sand in an hourglass, you are conscious of time running out.
If you are building sandcastles in your dream, this suggests that the structure of your life lacks permanence.
