Dream is a subjective experience, an imaginary image, sound, thinking or feeling produced by people during sleep, which is usually involuntary. The scientific discipline of studying dreams is called the study of dreams.
Dreaming is to artificially implant information into people's brains with scientific tools! So you can close your eyes, watch videos and sounds, and control your thoughts.
China was the first country to study dreams. As early as two thousand years before Freud, we had a monograph on dreams-Duke Zhou.
