Humanity had actually done considerable research into dreams. Well, "considerable" referred to the Earth Era. For humanity today, Earth Era research could only be considered somewhat developed.
Of course, the general descriptions were more or less the same; only the depth of research differed.
According to humanity's own theories from the Earth Era, dreams were a continuation of daily life. Of course, that was merely Plato's personal view. Psychoanalyst Freud said that dreams fulfilled repressed desires through distortion. Physiologist Thompson believed dreams were a normal form of neurosis; dreams allowed each of them to go quietly and completely mad every night of their lives.
There were all kinds of theories. After modern medicine developed, the concept of dreams came to be seen more as psychological imagery caused by localized brain tissue failing to completely cease excitation during sleep—a crossover, overlap, and fusion of physiological and psychological activity.
By that explanation, the content of dreams was generally related to a person's waking consciousness and impressions of life.
Yet Yue Yuan's case clearly was not. The things he encountered in his dreams had nothing to do with what he thought about during the day. He had never even seen some of the scenes before, such as that dream of the absurd rural setting.
Such scenes seemed more like images his brain had assembled on its own after extracting information from latent memories—more like the brain's own imagination, the result of some joint effect between the subconscious and consciousness.
Thus, Yue Yuan deeply suspected that something was wrong with him. Perhaps there was even a problem with his brain nerves. Of course, it could also have been a psychological problem, some kind of mental illness.
Therefore, Yue Yuan planned to first visit scientists specializing in Mental Consciousness at the Academy of Life Sciences
