When we asked students what they want to be, they often talk about unusual jobs, things like teachers and doctors. But if you think about it, many people don’t plan to do their jobs. They just start doing them by accident. We have talked to two people with unusual jobs.

　　Scientists believe that we have different kinds of sleep. One kind is called R.E.M. R.E.W. stands for rapid eye movement. During this kind of sleep our eyes move quickly, even though they are closed. Although we are asleep, there is a lot of brain activities. We probably have dreams at this time.
