Hard to say. You'd have to look into the background and the author's statements to determine if it's truly based on reality. Maybe it's a blend of fact and fiction.
It's actually not based on a true story. The plot and characters are crafted to tell a unique fictional tale that engages the readers' emotions and imagination.
The breathing tube in the man buried alive story is crucial as it's his only link to survival. It allows him to get the air he needs while being in such a dire situation. Without it, he would surely suffocate.
One possible theme is perseverance. Since it's based on a true story, it likely shows how someone overcame difficulties by just keeping at it, with breathing as a symbol of their continuous effort.
There could be a mix. In fictional works like horror novels or some very dark and extreme movies, there might be stories of this nature. But in real life, while there have been historical atrocities, the idea of specifically a girl being roasted alive is not something that is widely known as a common real - world event.

There was this girl who always had her headphones on. One day, she sat by the window. She took a deep breath in, and the music in her headphones seemed to amplify. It was a beautiful melody.

With each inhale, she felt more alive, and with each exhale, she drifted further into the story the music was telling.
