Dreams about being blind or dreams in which someone else is blind only rarely indicate the state of physical blindness.
As a dream symbol, blindness represents lack of awareness, either being truly unaware of something important that is occurring in one’s life or “turning a blind eye” to something about which one does not wish to know. Also, because our culture associates blindfolds with firing squads, blindfolds may indicate the sense of carrying out an execution, or of being executed.
