They are a special font that you will see in print, (whether in books, magazines, or on websites). Italics are used when you need to emphasize the title of something, or the name of a program, or certain other brand names-- note that some sources will say you should use the underline, but others prefer italics. Italics look like this: Nate Silver is a columnist who writes for the New York Times. His favorite TV show is Dallas.
The Stylebook is not a tool per-say. It is a guide to make known the intended Style for question wordings and answers.
It depends on what sort of story you're writing. It maybe be helpful to but a dream sequence in italics, just as you might place a character's thoughts in italics. If you're able to convey clearly that what you are writing is a dream, italics are not needed, but again, italics may be a helpful choice for the reader if you go directly into the dream sequence.
I like your style is "j'aime ton style" in French.
