The contrast between spiritual and material power is seen as two pillars in dreams. Esoterically, for there to be two pillars in a dream highlights the difference between the masculine and the feminine. The left pillar represents the feminine, and is often seen as being black. The right is masculine, and is seen in dreams as white. Pillars mostly indicate a sort of support, so to become aware of supporting pillars indicates that the structure that we have given our lives may need some attention. One symbolism of a pillar is phallic, but another one is probably more accurate. We are able to create stability and to stand firm in the presence of difficulty. In dreams, to find that we are a pillar of the community suggests that we should be taking more responsibility for our actions. You may also wish to consult the entry for Column.
