As we all know, sleep is an important part of our lives. Without the proper amounts and type of sleep, fatigue and other problems can arise. Generally, we can clearly distinguish between a sleeping person and a person that is awake.

Each sleeping disorder has its own unique answer to this question. It is essential to understand sleep to fully appreciate it. However, many aspects of it remain a mystery. We do have some degree of understanding of sleep. Within our sleep cycle a type of unusual sleep occurs, REM sleep. During this cycle the periods of…show more content…

It is fascinating that at this point, REM sleep, where dreaming is frequent, the body shuts itself down. If, as suggested in class, the I-function is active at this stage, it is interesting that all body movement is inhibited. During other stages in which there are synchronized EEGs, and the I-function is not supposed to be present, the body does not inhibit all motor activity. This seems to imply that when the I-function is present it will control the body as it sees fit. One of the more ubiquitous parasomnias is sleep talking or somniloquy. This disorder is characterized by often nonsensical or difficult to understand verbal vocalizations during sleep. The person may carry on conversations and seem to speak as if they are awake.
