According to Roman tradition, the god Hermes invented writing after seeing the different shapes cranes make while dancing and flying. The crane has always been considered an emblem of longevity and wisdom. Because it flies high over the dirty and dusty world, it is considered pure, clean, and of blameless character. It is a good omen to dream of a crane, as this means that you will fly high in your career. To dream of two cranes flying together is even better, as this means that others are supporting you in your ambition to progress in your life and career. It is not a good omen to dream of a crane flying away from you, as this portends the death of someone close to you.
