Spiritually, blindness is a form of ignorance. It can suggest the irrational. It is also a form of initiation. Intellectually we may be aware of certain facts, but choose not to use that knowledge in the most appropriate way. If we ourselves are suffering from blindness in a dream, there is an unwillingness to 'see', i.e. perceive something. We have lost sight of a goal or objective or we are seeing qualities in ourselves that we don't like.
