The underwater world - our subconscious, last, the world of feelings and desires; depth of internal life and various enlightenments, intuition.
The whole world to see - means sadness and tears.
As we progress spiritually we become conscious that, just as on an individual level we belong to the family, so the world belongs to the Cosmos. Being aware of the world in this sense means we must take responsibility for the way the world functions. To dream of other worlds and dimensions suggests different ways of experiencing our own lives. We perhaps need to become less rigid in our opinions. The world represents the area of experience in which one lives, and our everyday activities. Often to dream of a world beyond our sphere of influence suggests the necessity to take a wider viewpoint in a situation around us. Consult the entry for Globe for additional information.
