This is the first of the vivid, supernatural dreams that Ruth has after she starts reading Nao’s diary. The temple she sees in her dream, and Jiko’s office, are both exactly like places that Nao will describe later in her diary. However, Ruth hasn’t read these descriptions yet, so it is odd that she sees these places in her dream. In these supernatural dreams, Ruth seems to be traveling to another place and time, showing that her life has become deeply intertwined with Nao’s.
