But what about the quite meaningless dreams one sometimes has? They are due to the condition of the mind. If the condition of the mind is not harmonious, if its rhythm is not regular, then the dream is so mixed up that one cannot read it. It is just like a letter written in the dark, when a person could not see what he was writing. But all the same it is a written letter, it has an idea behind it. Even if the very person who wrote it in the dark room is not able to read it, it still remains a letter. When man cannot understand the meaning of his dream it is not that his dream has no significance; it only means that his own letter has become so confused that he cannot read it himself.
