Dreams

  On Wednesday we watched "What are Dreams?"  It was a movie made by Nova. I thought that this movie was good.  I learned some interesting things about dreams. I learned the when we go to sleep we have four stages that we go into before we start to dream. Stages 1 and 2 are light sleeping, then in stages 3 and 4 we are  actually asleep. From stage 3 and 4 our sleeping stages go backwards; we go stage 4,3,2 and 1. Then we fall into REM sleep, where our bodies go numb and we start to dream.
 
  I learned that some people suffer from REM sleep disorder. These type of people act out their dreams and don't even know that they are doing it. They feel that they are sleep and are not aware that they are acting out their dreams.  There is another rem sleep called non rem sleep. What happens here is that we just sleep through our dreams and we don't dream. One thing that is good about non rem sleep is that it helps people study while you sleep because whatever you were trying to study before you went to bed, your brain studies it while you are sleep. It was amazing to see what made our nightmares. This was due to having too much REM sleep. They say that nightmares can be good because  these dreams are helping us prepare for a situation that could happen in the regular world.  Since it is a nightmare we act it out in our dreams, and when this happens to us in the real world we are prepared for it.
