Author Glenn Van Ekeren, in his book “The Speaker’s Sourcebook”, published in 1988; in a freezer that is actually broken but doesn’t work”,just because he believes” It tells the interesting story of a man who froze to death. There is no personal information about this man, whose name is unknown, only his story. This story is spreading more and more among the people and like a word of mouth game every listener adds something new to the story.
The story is told in the respected magazine Reader’s Digest, that it is real and that the name of the person frozen to death was also mentioned. Nick Sitzman The story becomes even more impressive when the rumors are added that it is true, and people no longer have any reason to believe that the story is true.
Nick Sitzman and his questionable story:

Nick Sitzman; A strong, healthy and ambitious young man with a hardworking and loving wife, two children and many friends. is a railway worker†On a summer day, train crews finish their work an hour early. While doing one last check on the wagons, Nick accidentally in the freezer remains locked. When he realizes that the rest of the workers have left the field, he panics and starts screaming, but no one hears him. He thinks the temperature in the freezer is zero degrees and if he stays inside he will freeze to death in no time. To tell his wife and family what happened to him, he scrapes the following into the ground with the knife he found in it: It’s so cold, my body goes numb. I wish I could sleep. These may be my last words.
In the story’s continuation, morning teammates Nick frozen to death somehow they find it. When they look at the freezer temperature records, they realize this is impossible. Because the freezer Nick is locked in is broken and hasn’t worked for the past week, including that night. The temperature in the freezer has never been below 10 degrees Celsius. As a result, they come to the following thought; The cold didn’t kill Nick, Nick killed himself by the power of his thoughts. In another version of the story, Nick Sitzman in a restaurant to work. Likewise, it will remain locked in a broken and non-working freezer; He thinks the freezer continues to cool and at the end of the story he freezes to death.
The relationship between the pygmalion effect and the story of the frozen man

It’s about whether the story itself actually happened. doubts although there is Pygmalion effect This story is often told when explaining the theory of the “self-fulfilling prophecy” or otherwise. This theory, one of the theories of social psychology, is defined by the sociologist Robert K. Merton as “New behavior resulting from the misevaluation of events or conditions causes the wrong”. In short, what you believe influences your behavior, and these new behaviors make what you believe in.
allegedly Nick Sitzman believed so much that he would freeze to death, that the prophecy finally came true and Nick actually died. But he didn’t even leave a real name.
Is the story true?

In the investigations, this story was not found in the archives of Reader’s Digest magazine. Whether a person named Nick Sitzman is really alive or not. there is no proof†If you are locked in a freezer, you may begin to believe that the freezer is still working and getting very cold. It is even possible that you will have a heart attack because you are afraid, but it is not physiologically possible for you to freeze to death in weather conditions above 10 degrees Celsius.
In spite of everything, let’s say that such a situation actually happened, shouldn’t the scientific-medical community keep all the records of this event and investigate it? But the interesting thing is that there is no hospital record or autopsy report on this incident. All we have is an “evidenceless” story.
