In Jamie Sams' book Animal Medicine, the Owl is depicted as Deception, which is really an opposite of clarity and knowing. The Owl is often depicted as Wisdom.
I think of it as our inner knowing being aware that we are often deceiving ourselves, and as it says in the Serenity Prayer, and the wisdom to know the difference.
