To dream that you are blind represents your refusal to see the truth or your lack of awareness to a problem. Perhaps you are rejecting something about yourself or your situation. Are you refusing to see any other point of view except your own? Consider the pun, “turning a blind eye”.
To see a blind person in your dream suggests that you are letting opportunities pass you by.
To dream that a blind person has regained their sight in one or both eyes implies that you do not need to be able to physically see certain things in order to “see” things. You need to trust your instincts or intuition.
