Some people are actually self-conscious of the fact that they're dreaming when they are in the midst of their dreams. It changes the way you relate to the things going on in the dream, whether they're frightening or not. It changes your total perspective. That's the way world views work. They interpret the world for you and they instruct you on how to act and how to think about the world around you.
Christians have a world view.
We believe, for example, that God is real. We believe that the world is a result of God's purposeful creation, that God is a person, and that He created personal qualities in human beings. Because God created with a purpose, there seems to be some sense to our existence. Although there are a lot of other details involved in a Christian world view, this sense of purpose is essentially where it starts. The Christian world view says that man was made in the image of God by a direct act of God.
