I've had similar images (movie shorts I call them) that are on repeat. I talked to my pdoc about one in particular (almost exactly the same as yours) because it frightened me so badly. He said it wasn't anything to worry about. It was likely brought on by stress and it was my minds way of stopping the stressful thoughts, and wanting the pain of stress to stop. The other "movie shorts" that I get tend to be things that would only be possible in a cartoon world (Like Wile E. Coyote and Roadrunner). Ok, I just seriously dated myself there! So those don't frighten me so much anymore. Plus I've had them for as long as I can remember, and that's over 50yrs.
Increases in my meds have helped and finding ways to lessen the stress.
