Can people control dreams?

< p >< / p >< p >Dreams usually seem so incredible, often with strange combinations or sudden scene changes. Dreams seem to have no causal law, nor are they limited by time and space. So is there any connection between absurd dreams and real life? If there is a connection, can we influence the content of dreams by controlling the conditions before and after sleep? < / p >< p >the earlier researchers in this field are Demente and Walpert from the Craitman Laboratory of the University of Chicago in the United States. At first they noticed that most of the new subjects who had just arrived in the sleep lab often incorporated the novel environment of the sleep lab into their dream plots when telling the story of their dreams. Obviously, changes in sleep conditions are reflected in dreams. Demente and Walpert learned from it and designed a series of interesting experiments. The method of the experiment is very simple, which is to change the environmental conditions of the subjects during sleep to see if it will be reflected in their dreams. The whole experiment was divided into three parts, first drenched in cold water, followed by bright light, and then music. As a result, only 42% of the subjects' dream reports involved water, 23% talked about light, and 9% mentioned music. These figures do not seem to explain the problem very well. < / p >< p >many scholars have done related experiments, and as a result, they have made the same number of different explanations, but one thing seems to have become clear, that is, when the awake environment encounters some special changes, new content related to it will be added to the dream. However, the focus of the current question is how to accurately grasp the inevitable relationship between environmental stimuli and dream content, and only by doing so can we achieve the idea of controlling dreams. < / p >< p >later, two American scientists, Witkin and Lewis, measured dream content by stimulating the real world. The stimuli they used were four films, one in which a pregnant woman was giving birth, one in which primitive tribesmen cut the penis foreskin of a male teenager with sharp stone slices, and one in which the female monkey tore up and eaten the dead baby monkey. and another is an insipid landscape film. < / p >< p >results according to the subjects' reports, the contents of the first three films were mostly incorporated into dreams, while the plain landscape films were not at all. The above experiments seem to show that the external stimuli in real life are more intense, and those stimuli are more likely to appear in dreams, which has been agreed by many scholars. < / p >< p >the only answer to the question of whether people can control the content of dreams so far is that external stimuli before and after falling asleep seem to be programmed into dreams. However, it is related to a variety of physiological mechanisms and its regularity, due to too many changing factors, it is difficult to standardize it at present. Scholars in this field find it complex and difficult to influence dream content by controlling the conditions before and after falling asleep. Therefore, we first need to have a more accurate method to measure the content of dreams, and then we can understand the meaning of dreams and finally achieve the goal of controlling dreams. < / p >
