Crane's symbolism includes longevity, intelligence, innovation, and honor. Cranes have been widely revered in many cultures for centuries. People with the Crane totem are secretive, very protective of themselves and their families. Cranes mate for life and can live for decades, as such they symbolize loyalty and longevity.
They are long and graceful as they fly fully extended with their necks outstretched and their legs straight out behind them. This symbolizes touching the past and looking towards the future simultaneously.
When Crane comes into your life you are being challenged to use your past to better your present/future. Crane people can be fierce fighters when neccessary and because of this they can reach new heights. Crane people are often called upon to take something from their past and improve upon it, using innovation or new methods to solve old problems.
A Crane flying in your dreams is said to be a good omen, but if it is on the ground it is a sign of troubles of your own creation.
