Often, my characters will be thinking and flash, some image appears to guide their thought. An example:
I promised her. No. You pinky swore. You swore you’ll drudge down to the library and study. She even prepared a worksheet for you. The worksheet dimly lit appeared in my mind. A poorly lit study cube, somewhere in the basement of the library. I sat alone, in a four by four room, afraid to let any of my possessions touch the grey felt walls.
Every time I try to express this, I write either "It appeared in my mind," or "An image flashed," then I go on to describe the image.
How else can I express this?
