Birds in dreams commonly symbolize freedom and the desire to rise above a situation for a clearer view. A bird in flight can reflect an ambition taking shape or a sense of release you're craving, while a caged or grounded bird often points to a freedom that currently feels out of reach. Pay attention to the bird's mood -- it usually mirrors your own relationship to being unbound.
The stars should be used in the construction of cities; in the construction of houses we must use the planets. - Ptolomeus
