The blind can’t see things. Blind people, meaning loss of ability to distinguish.
If you dream of being blind, it means that friends and relatives around you are not credible, and you should polish your eyes.
Dreaming of a blind person knocking on the door, suggesting someone else’s negligence or omission, will send you money. In the near future, you may have unexpected incomes, such as the amount of money that someone else has missed, and the good business that others have inadvertently missed. You have to make a judgment.
I dreamt that a blind person stood at the door of my house, suggesting that I would reunite with the parting person, or that a guest would come to the door.
