Section C Compound Dictation
Sleep is part of a persons daily 36activity cycle. There are several different stages of sleep and they occur in cycles, If you are an 37average sleeper, your sleep cycle is as follows. When you first drift off into slumber, your eyes will roll about a bit, your 38temperature will drop slightly, your 39muscles will relax, and your 40 breathing will slow and become quite 41regular. Your brain waves slow down a bit too with the alpha rhythm of rather fast waves 42predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so as you relax more and more you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep the slower your brain waves will be. Then about 40 to 60 minutes after you lose 43consciousness you will have reached the deepest sleep of all. 44Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.
You do not remain at this deep fourth stage all night long, but instead about 80 minutes after you fall into slumber, your brain activity level will increase again slightly. The delta rhythm will disappear to be replaced by the activity pattern of brain waves. 45Your eyes will begin to dart around under your closed eyelids as if you were looking at something occurring In front of you. This period of rapid eye movement lasts for some ~ to 15 minutes and is called REM sleep. It is during REM sleep that most dreams seem to occur. 46Provided that you do not wake up during the first sleep period, your body will soon relax again, your breathing will grow slow and regular once more .You will slip gently back from stage I to 4
