Dream is a very interesting thing. As what is dream? Having a dream means that the mind is too excited. While dreaming we experience that has happened with us during the day or the recent time once again but in a very rapid way. We even can see things that were not important for us in real life. But
our brain is so strong thing that it even can change the plot as we want.But when we sleep without dreams – our brain relaxes after a day intensive work. So the dream is a very complicated thing.
