This will be weird.
Lately, plot points are coming into my head in a new way.
The photo above is the closest I am able to come to illustrating what it is.
Here's how it seems to work, using yesterday as an example: I had already written a scene. Yesterday, I rewrote it. I thought it was finished, but I still wasn't totally sure why it was in the book. It seemed a kind of. . .departure. Then, on the drive home, a sentence fell vertically into my mind. That's exactly how it feels/seems. The sentence was something like, "He thinks she lured him away so people could hurt his family while he was gone." It was an aha for that scene and it explained why it is in the book, something I didn't know before that vertical sentence dropped out of the blue.
One more thing: the vertical sentences drop into the very center of my head, and there is a little physical sensation. If I could move that silver thing further to the middle of the photo, I would, to give you the correct impression.
Told ya it would be weird.
