Psychoanalysis

The Secret Life of Walter Mitty is written to help you feel like you are the character while reading it. The character, Walter Mitty, has a creative mind and seems like "he hated these weekly trips" and would often go into a very intense day dream often focused around him in several situations that he probably has only found himself in due to whats just happened to him springs him into thinking of some type of relation.
His first day dream is ended with his his wife telling him to slow down, ironically in his day dream he was trying to go fast, in a plane, his whole crew hoping that they would survive his crazy antics. Although it doesn't say his name in the first day dream, you end up recognizing it because of the last sentence where he continues to think of the event after his wife broke his thought: "Walter Mitty drove on toward Waterbury in silence, the roaring of the SN202 through the worst storm in twenty years of Navy flying fading in the remote, intimate airways of his mind."
Most of the day dreams also have repeated aspects like the "pocketa-pocketa" sounds that are much like the sounds you get stuck in your head and end up adding into different day dreams you have.
Its Psychoanalysis because you are taken into most of the characters perspective and put into a train of thought where you are reading how they are thinking and what caused them to think that way. It makes it interesting and easy to read because you can recognize the actions by the characters as something you might do in real life.
The story is seperated so you can experience the day dream he is having, and then have the feeling of being cut off in the middle of your own day dream when it switches to the next paragraph, usually with someone talking to you. At one point they show this when Mitty claims Ms Mitty through off his train of thought, first muttering something to her about something associated with his day dream and then telling her " 'I was thinking,' said Walter Mitty. 'Does it ever occur to you that I am sometimes thinking?' "
