Dream meaning of square
To see a square in your dream signifies strength, solidity and stability. Alternatively, a square indicates that you are limited in expressing yourself. Consider the idiom of “being square”. Perhaps you are being too conventional, unhip or dull. To see a square in your dream may also mean that you are “back to square one”. You need to start over and go back to the beginning.

The square, as the expression of the quaternity, is a symbol of the combination and regulation of four different elements. Hence, it corresponds to the symbolism of the number four and to all four-part divisions of any process whatsoever.
Psychologically, its form gives the impression of firmness and stability, and this explains its frequent use in symbols of organization and construction.
The four Elements, the four seasons, the four stages of Man’s life, and specially the four points of the compass, are all sources of the order and the stability of the world. This does not contradict the feminine character which Chinese, Hindu and other traditions ascribe to the square, since it corresponds to the earth, in contrast to the masculine character of the circle (and the triangle).
In Egyptian hieroglyphs the square signifies achievement and the square-shaped spiral denotes constructive, materialized energy. However, the square resting upon one of its corners acquires a dynamic sense which is quite new, implying a change in its fundamental symbolism: during the Romanesque period, it was used as a symbol of the sun, comparable with the circle.
Squares suggest stability, which in a dream may reflect a felt state or indicate a need for more stability.
Squares also signify strength and solidity (square jaw or square shoulders).
Eventual success and security will be yours if your dream featured anything in this form.
