I think a similar effect was described by Daniel C. Dennet. Imagine a row of lights next to each other. The leftmost one blinks, then the one to the right, then the one to the right, creating an effect of a smoothly moving light dot from left to right (similar to how animation works). What does your brain see in the period between the blinks? Because it perceives the light as a smooth motion, and not as discrete jumps, it must "see" a virtual non-existent light in between two real lights. But if everything in your brain happens chronologically, how would it know if the light to the right would light up or not? It must have "backfilled" that information into your memory/perception after seeing the right light blink.
