happens, the nerves that usually carryinformation from the world around us shut down(Guiley).If the dream happens during the REM phase of sleep, the person sleeping willexperience an increased heart rate and a temporary paralysis. To prevent the sleeper fromacting out the dream, the brain freezes the muscular activity. Experiments have been doneon cats where the nueral fibers that freeze the movement during REM sleep wereremoved. This resulted in the cats walking around and acting out there dreams. Somepeople do act out there dreams. This disorder can be treated by a drug called Clonazepamwhich is also used to treat epilepsy.Dreams are different according to when the dream occurs in relation to the periodof sleep. During the REM stage of sleep and at other times or non-REM sleep. There arefour stages of sleep. As the sleeper goes through the stages of sleep the brain wavesdecrease in frequency. After the sleeper goes through the four stages of sleep, the sleepergoes back through the stages until they are back in stage one. This stage bone is called theEmergent Stage One. This is the time in which most of the REM dreaming occurs. In early 1953 is when the physical science of dreams really began when researchersat the University of Chicago discovered physical signals like rapid eye movement and brainwave patterns that signaled that dreams were in progress. Most all of the research sincethen has focused on the REM stage of sleep. All mammals, and even a few birds andreptiles go through the REM stage of sleep. In humans as we get older less time is spentin the REM stage of sleep. Fetuses spend most all of their time in the REM stage and newborns spend an average of eight hours a day in REM sleep. Fifty percent of sleep ofinfants and small children is spent in REM sleep. Adults sleep is usually about twentypercent REM sleep, and for older people only fifteen percent of sleep is spent in the REMstage of sleep. Many scientis...
