It came out of a conversation I had with raiblu the other day. He was concerned with the length of the novel, and I suggested he add several paragraphs to each which fully illustrate something, then slam the door shut on that something by declaring that it doesn't exist or didn't happen. In other words, you paint a picture with words, then slowly erase it until the reader realized it never was. Like so:
"He opened to door to the grand hall, where many fancily dressed nobles were dancing, talking loudly, or otherwise cavorting. One woman with jet black hair and pale skin caught his eye and invited him toward her with a smile. However, she didn't actually smile, or even exist. In fact, there wasn't a party, and he never opened the door. Nothing in this paragraph happened."
Naturally, we wouldn't typically want to use this little hunk of messed-up narritive in fiction. thetakogun asserted that this style of writing would be useful when we have a character or atmosphere that is distorted by psychosis. I totally digged that! Kudos to him!
Run granade, run.
One more thing: I've been uncharacteristically quiet lately because one of my friends are going through something really bad. If the worst happens, there'll be a post about it.
