One of the jew "survivors" wrote a book and described basically this exact thing in one of the "death camps". Of course it never existed, but jews never let the truth get in the way of a good story.
Here's a post from u/SystemGay where I saw this. Book is called "Inside the Concentration Camps" and the testimonies in it are all considered historically accurate, despite being wildly different stories and clearly without any fact checking done by the publisher at all.
