why is mrs. schachter the first to break down on the train?

Madame Schaechter is in the same train car as Eliezer during the initial deportation to Auschwitz. She had been separated from her husband and two older sons, and she is accompanied by another younger son. She loses her mind during the journey and screams hysterically and repeatedly about a flaming furnace that she apparently sees in the distance. She terrifies the other occupants of the train, and she is repeatedly beaten by young men trying to silence her. She is old but also has heard about the flames of the camps.
