Walter Mitty slips into daydreams in the story frequently, but they are brought on by different circumstances. What causes Walter to go into his daydream scenarios during the story?
-Walter drifts off to sleep multiple times in the story and that causes his daydreams
-A certain sight or sound in the real world snaps Walter into his elaborate daydreams
-Walter is reading a newspaper and each story in the newspaper draws Walter into his daydreams
-Walter is actually dead, and all of the story is a dream
PLEASE HELP
