I had this dream about a year ago. I don't think I really need any help with the interpretation as I think you'll see that I got a pretty good handle on the meaning.
I was in Auschwitz. In my dream, I was being herded through a courtyard with hundreds of other malnourished skeletal looking people. Everyone was bald and dressed in rags. In my dream, I was walking through a courtyard where they were executing people by gunfire against a wall lined with bricks of human hair.
Everyone was sobbing as we were stripped nakid and forced into a room. I looked up and saw that I was in some sort of shower/gas chamber. Suddenly the gas started flowing into the room. A little at first, then more and more. I held my breath as long as I could. I was hoping that I could hold my breath until I passed out and then I wouldn't feel the gas, but it was no use. I started to panic when I realized that I could smell the gas. It was getting thicker and thicker and I started to choke on it. My choke reflex was so strong that I started to gag and choke in real life and woke myself up.
TO FIND THAT BY BOYFRIEND HAD PASSED THE NASTIEST FUCKING FART EVER. His fart was so fucking nasty that I actually incorporated it into my dream and was LITERALLY choking on it. Now I call his ass air "toxic nerve gas".
