What does madame schachter imagine she sees during the train ride?

During the train ride to Auschwitz, Madame Schachter imagines she sees a fire burning in the distance. She frantically warns the other Jewish passengers about the flames, screaming that there are burning bodies and a crematorium. Her visions reflect her deep sense of foreboding and represent the horrors that await them, although initially, the others dismiss her as delusional. Her prophetic cries foreshadow the grim reality of their fate in the concentration camps.
