What is the author's style in In His Own Write by John Lennon?

The language in the story is fictional in many areas and there are times when words have been changed with other words to confuse the meaning. The author had intended his writings to both make the reader think about the meaning of words and to laugh. Often the pictures that are given from the story are dark ones that end in death, but the situations that the characters are in and the things they go through often qualify as humorous.
