I dreamed of scooping up stolen paper in the toilet,

At the level of consciousness, the way we think about problems is abstract and generalized. Similarly, at the level of consciousness, we are selective in how we observe things. For example, when we listen to a person, our main focus is on what they are saying.

At most, you can pay attention to whether his voice is unusual. In the subconscious, the "primitive man" is like a well-functioning video camera that is turned on day and night, and it will record every word of that person, along with the tone of voice, every subtle action and analyze. In this way, the slightest abnormality in the other party's actions will attract the attention of the "primitive man".

In other words, the observation of people and things by "primitive people" is much more detailed and comprehensive than that of us at the level of consciousness. So he might find something that we didn't notice.

Again, at the level of consciousness, we tend to deceive ourselves. People have language and thinking, and they are much smarter than animals, but it is precisely because of these that people can also deceive themselves. Lu Xun said something of this kind of meaning:

Lions, tigers and wolves want to eat people, they just eat. I will never first say some reason why I want to eat you and why you want to be eaten by me. But people are different, it is obvious that people want to harm people, and they still have to talk about the reason that they eat people in the name of justice and justice.

There are too many things for people to deceive themselves, obviously they hate his father, but when they think that their father has an inheritance, they need to lie to themselves and say that I have a sense of responsibility and filial piety, so I will be so good to him; obviously has intentions for girls, but he lied to himself that we are just friends of the opposite sex, exchanging ideas and talking about ideals; obviously felt that her wealthy husband was having an affair, but she was afraid that she would be abandoned by her husband if the truth was exposed, and she would lose her material enjoyment, so she lied to herself that her husband was too busy with work if she didn't come home. But in the heart, the "primitive man" is more likely to face reality, and he knows what the truth is. Therefore, primitive man can tell us many truths, prompting us to face reality more and solve problems rationally without escaping from reality.

Also, the "primitive man" is closer to human instinct, and it knows better what you really need. Due to self-deception and interference by various concepts, people often do not know what they really want, and only blindly pursue some things that everyone in society is pursuing, and cannot see the true desire of their hearts. "Primitive people" do not, at least not make such mistakes.

Dream interpretation may be likened to diving into the sea, diving from the surface of the water, diving into the depths of the heart, diving into the unknown world, and from then on obtaining a pearl - this pearl is knowledge and wisdom.
