Franz Kafka wrote The Metamorphosis, a story where a salesman wakes up one day to find he's been transformed into a man-sized roach. The transformation is never explained and nobody reacts very strongly to it because it's an analogy for the character's isolation. It's kind of a funny read if you go into it thinking, this guy is now a roach and nobody is freaked out about it, but if you think about it as the character experiencing something nobody else can understand, it makes sense.<br/><br/>It's a pretty famous story! Maybe you've heard the first line before?<br/><div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">One morning, upon awakening from agitated dreams, Gregor Samsa found himself, in his bed, transformed into a monstrous vermin.</blockquote><div class="quotefooter"><div class="botslice_quote"></div></div>
