Question of the day. Where is the most uncomfortable place you have ever slept?

Without a doubt my answer would have to be sleeping on a moving train while traveling abroad. In my younger days, I once took a 20-hour train journey while I was visiting some friends in Kazakhstan. I thought that taking the train across the desert would be relaxing and a beautiful sightseeing experience but my expectation turned out to be different from reality. As the train pulled in at the station I remember thinking what am I doing? Because the train looked honestly ancient.

Upon boarding I quickly found out that my private cabin was smaller than advertised and everything in that room including the bed looked rather unpleasant. I tried to accept the situation and lower my standards but as soon as the train started to move I knew I was in even deeper trouble because everything started to shake and that shaking did not stop. It's a funny memory now but at that time I was feeling pretty discouraged and exhausted because I couldn't get much sleep on that bumpy train ride. It's a memory I'll never forget.
