Blindness in a dream usually represents ignorance.
If you dream that you are blind, your dreaming mind is telling you that you have not been aware of, or you have not been paying attention to something that should be obvious to you.
A dream that you are blind is a message that you should be more observant in real life. Perhaps you have not been paying enough attention to people who are close to you.
If you dream that someone else is blind, you feel that other people do not pay attention to you or that you are unable to communicate with them.
Blindness in a dream can also symbolize spiritual or religious ignorance.
