The aim of my dissertation project is to undertake a diachronic and intertextual investigation of sword dreams in ancient and medieval Japanese texts, ranging from Japanese mythology to war tales and Noh theater. In Japanese mythology sword dreams play an important role, functioning as a symbol of the legitimation of imperial power by the deities. Sword dreams are also an important motif in war tales, namely the Heike monogatari and the Taiheiki, compiled in the Kamakura and Muromachi periods respectively. In addition, I will examine sword dreams in the so-called “dream Noh plays” (mugennō) established by Zeami (1363-1443) in the Muromachi period, whose functions differ quite considerably from those appearing in the mythology and in war tales. Through an analysis of the sword dreams in these works, this survey diachronically traces the transformation of worldviews from ancient to medieval Japan.
Since the dreams in all these works have in common that they connect this world to the otherworld by exhibiting specific spatiotemporal correlations, my analysis involves the methodological approach of the “chronotope” – the correlation between time and space (Bakhtin 2002). Regarding space, I investigate the relationship between this world and other worlds (the world of deities, the world after death etc.). Regarding time, I examine how dreams connect living spaces in the past, the present, and the future. Furthermore, my research also involves other time-related theories (e.g., Fraser 1978) and approaches related to collective memory (e.g., Erll 2010) in order to diachronically examine collective and individual aspects of the transformation of worldviews, including the views of life and death.
