I dreamed that someone dug an ancient tomb and found an old man.

According to the Duke of Zhou, if you dream of a living person digging a grave, the grave digger will live a long life. According to modern theory, dreams are subconscious, and what the brain has not done is done by the cerebellum. Thinking and dreaming day and night may be something you have encountered or thought of recently. It doesn't make any sense. Don't be superstitious Sweet dreams!
