When we sleep I feel so happy and rested. Everyone needs at least nine hours of sleep. Until now scientists have discovered new things about dreaming. Why do we dream? Where do our dreams come from? Do they have meanings? When we dream we are organizing information from the past. It was only 55 years ago that neuroscientist really started to investigate about dreams. When we dream we are in REM sleep or in a rapid eye movement stage. Our muscles paralyze and we are extremely relaxed and calmed. I find dreaming hugely fascinating and really interesting because it is a mystery that everyone wants to know about. This video showed and explained that we dream to learn a lesson or to be prepared for something strong. For example when we dream that someone dies, it is kind of preparing us so that it will not be that shocking later on. Some people like Tom for instance in the video shown act out their dreams. He was highly energetic while dreaming and sometimes aggressive. His wife wanted doctors to treat him. I am really afraid of dreams because they can sometimes be so crazy and frightful. I learned so many things from this video that I had no idea about.
