This is one dream symbol on which practically every source agrees. It represents the dreamer's basic ambition, but the interpretation depends on the details of the flight, so the surroundings, weather, etc., must be considered along with the action. As a general guide: If you successfully maintained your flight at a low to medium height, you can expect to achieve your goal without much difficulty. If you were trying (or straining) to reach a high altitude, the dream is telling you that your grasp is greater than your reach, and you would be wise to alter your course.
