Based on your reading of the passage, make short notes in each of the boxes in the flow-chart showing different characteristics of dreams. (No. 1 has been done for you):

Dreams have fascinated philosophers for thousands of years, but only recently have dreams been subjected to empirical research and scientific study. Chances are that you've often found yourself puzzling over the content of a dream, or perhaps you've wondered why you dream at all. First, let's start by answering a basic question: What is a dream? A dream can include any of the images, thoughts and emotions that are experienced during sleep. Dreams can be extraordinarily vivid or very vague; filled with joyful emotions or frightening images; 

focused and understandable or unclear and confusing. Why do we dream? What purpose do dreams serve? While many theories have been proposed about the reason and function of dreams, no consensus has emerged. Considering the time we spend in a dreaming state, the fact that researchers do not yet understand the purpose of dreams may seem baffling. However, it is important to consider that science is still unraveling the exact purpose and function of sleep itself. Some researchers suggest that dreams serve no real purpose, while others believe that dreaming is essential to mental, emotional and physical well-being.
