An eagle in a dream typically points to vision and ambition -- the ability, or the wish, to see a situation from high enough up to understand it clearly. Watching an eagle soar can reflect confidence in a goal you're pursuing, while one that struggles or is caged may point to ambition that currently feels restricted. The eagle usually asks what perspective you need before moving forward.
The biggest difficulty with mankind today is that our knowledge has increased so much faster than our wisdom. (Frank Whitmore)
