Scientists believe that dreams are the result of the combined action of various central points in the brain that are responsible for various functions of the human body. Some people's brain cells are still active during sleep, which is the basis of dreams. Recent research results confirm that dreaming not only does Affects people's sleep and health, and is one of the physiological activities necessary to protect brain health. Which of the following, if true, would best support the above conclusion? ['In the study, subjects who were disturbed by dreams appeared anxious, easy to be nervous, and had short-term impairment of memory after waking up.', 'According to the questionnaire analysis, people who do not dream for a long time need more sleep than those who often dream, and half of them still feel tired after resting.', 'Surveys show that subjects who can fully describe dreams are more able to concentrate at work faster than forgetful dreamers, thus working more efficiently.', "Experimental researchers immediately blocked the dreaming brain waves when they were sleeping, and found that the subjects' blood pressure and body temperature increased significantly."]
