Bones are one of the integral parts of man, or indeed of most creatures. Spiritually, they represent structure and the basic building material of the physical realm. They often hold the key to our ideas of death and resurrection.
Psychological / Emotional Perspective:
To dream of a full skeleton indicates that we need to reconsider the structure of our lives. To be conscious of particular bones in the skeleton, particularly the joints, highlights the way we move or create.
Everyday Material Aspects:
Bones appearing in a dream usually indicate that we need to be aware of fundamental material. We need to ‘go back to basics’. To dream of a dog eating a bone means we need to consider our natural instincts. To dream of finding bones indicates that there is something essential we have not considered in a situation.
