There were some twins in our group who were so identical that we couldn't tell them apart. There were also people with physical deformities and one family, seven of whom were dwarfs. I had the misfortune of having the same blood type as one of the German soldiers. One day they took me and laid me on a table and put a tube in me and another tube in the soldier. They transferred my blood to him, which was very scary.
As they were doing these experiments, I was just grateful that it wasn't worse than I expected. I often felt dizzy. I don't know if it was the fear or the drugs and dyes that they had injected. The doctors never explained what they were doing. We were drained physically and emotionally. We lost a lot of weight, not only because of the diet but also because of our fear of what the next step would be.
