This article explores the dream descriptions submitted in 1973–1974 by former Polish prisoners of the Auschwitz concentration camp in response to a questionnaire sent out by Polish psychiatrists. These descriptions are being investigated as testimonies that represent the Auschwitz inmates’ experiences commonly regarded as “unspeakable.” Not only the dream experience itself, but also the respondents’ attitudes toward and beliefs about dreams are taken into consideration in an attempt to understand the impact of the Holocaust on the survivors. Their general inability (...) of comprehending the Auschwitz and post‐Auschwitz dreams seems to be the most important and significant aspect of their testimonies. The experience of dreams as completely strange and astonishing phenomena is being explained in this article in connection with the respondents’ ability and inability to recover from their Holocaust trauma.
