it sometimes is when the body is awake. One group of researchers decided to see what would happen if they stopped people from dreaming. As soon as the electroencephalograph (??μ?í?ò?) registered a dream pattern, researchers woke the dreamer. They did this all night for several nights, every time the person started to dream.
The experiment revealed that people who were unable to dream became nervous, easily upset, and hungrier. As soon as they were able to sleep without interruptions they lost their nervousness and became normal again; however, they then had more dreams than usual. It was as if they were catching up on their dreams. To check these findings, the researchers carried on a control experiment. Again they woke people during the night, but during non-dreaming periods. These people did not change their daytime behavior. And when they were allowed to sleep without interruptions (′ò??), the number of their dreams did not increase.
Experiments like these have caused scientists to ask if dreams serve a purpose. Researchers know, for example, that some people who go for days without sleep will suffer from hallucinations (????). Certain people even begin to show signs of mental illness. Some researchers believe that people become this way because they cannot have their usual numbers of dreams. According to this theory dreaming helps people to lead normal lives.
