All my real dreams have been stories, however I've had a few dream like displays after waking up, but keeping my eyes closed. It's usually been repeating patterns of objects that change every 5-10 seconds, e.g fir trees, chairs, cars, hot air balloons etc. However, at least once, it was more akin to a film with people doing something in it like talking, driving vehicles etc. The display only appears in a small rectangular area on the right side of my vision, when I have my eyes closed and disappears when I open my eyes.
