Dreams. We all dream and they are so fascinating and can mean so much or very little depending on the type of dream you have. Why does the average dream last only a few minutes even though it seems like it went on all night? What about recurring dreams? How is it you are having a dream and know you're dreaming? All of these questions can be answered in this relatively short video about dreams. If you are a student and are studying 'Oneirology', this video is for you and is very interesting and educational.
