Spiritual Meaning:
There is a basic side of nature that needs to look up to something and this can be symbolized in dreams by a statue, which is representative of an idea or concept rather than a person.

Psychological / Emotional Perspective:
When emotion is not allowed proper expression it is ‘dead’and, therefore,  has solidified. Often in dreams this will take the form of a statue. If the statue comes to life, the emotion can be rescued.

Everyday Material Aspects:
Dreaming of a statue is to be linking with the unresponsive, cold side of human nature. We may be worshipping or loving someone and not getting any response. We come up against the knowledge that we have given value to something that no longer has significance.
