We tend to think of our dreams as being uniquely personal—nighttime stories built from our own experiences that help us process our day-to-day lives. While dreams can give us a look into our personal selves, scientists have collected data that suggests dreams make their way into our cultural fabric（结构）, showing themselves in ways that shape beliefs and expose collective anxieties.
Roger Ivar Lohmann of Trent University conducted research with the Asabano people of the rainforest of Papua New Guinea, a unique group who didn’ t have outside contact until 1963. His studies looked at how dreams shape their beliefs and actions.
According to Lohmann’ s research, dreams act as a sort of motivator or determinant of Asabano behavior. For instance, a dream may affect the way a person hunts or goes about treating medical conditions. The way dreams determine behavior is due to what Lohmann calls the “night residue” effect. This means that specific memories of dreams can affect the way a person acts when awake and inform their belief system.
Dreams also seem to have an effect on the way many define themselves within their own cultures, and how sometimes reaching a distinct definition can cause anxiety.
Matt Newsom of Washington State University spoke with college students in Berlin, and found many students had dreams surrounding conflicting views about their own identities（身份） in relation to what they saw as a return of German nationalism, which is a sensitive subject especially when we think of German identity as it’ s defined even many years after World War Ⅱ.
Many students had dreams that centered around anxieties like “Where do I belong?” Many students never talked with one another about identity struggles in their dreams, yet many reported having such dreams. Newsom noted that dreams can be helpful “for identifying （识别） unspoken social and historical anxieties present in a given society.”
All of this research suggests that dreams can do more than help explain the thought of a person; we can learn about entire cultures and collective attitudes as well.
