Art of a Killer
For those of you who are unfamiliar with some of the better known serial killers, John Wayne Gacy was one of the most prolific and infamous serial killers in the history of the United States. He was sentenced to death in the electric chair, which was carried out back in 1994, for the murder of 33 people. As the story goes, he could have continued for a lot longer – he was an organised killer and a sexual sadist who disposed of the bodies of his victims in the crawl space of his house. It was only when he ran out of room under his house that he started to dispose of the bodies in the local rivers, which ultimately led to his capture.
For most of us, sleep is nothing but a compulsory action that we have to do at least once a day, but for scientists who study it, the mysteries of sleep contribute to a plague of questions with hard to decipher, often inaccessible, answers. Questions such as what function does sleep serve and is there an internal mechanism controlling our sleep are among various possible questions that researchers in the field continue to scrutinize but in this particular paper we will examine the stages of sleep, their physiological differences and a number of the theories behind Rapid Eye Movement (REM) sleep.
