This presents a challenge to global communication strategy.
It's no secret that linguists and philologists have tried to create an artificial language that would be spoken all over the globe so as to erase the boundaries between nations.

This experience is an effect of memory that occurs because of iconic memory.
Explanation:
Iconic memory is a part of visual memory that lasts only for milliseconds. Everybody has experienced an example of iconic memory in their lives. For instance, when we turn off the lights and still have an a quick memory of what the room looked like when the lights were on. Or when we stare at our phones and then close our eyes, but can still "see" the phone screen from a moment ago. That is the same explanation for the appearance of a trail of light when the light is physically only in one place. Our brain can still "see" where the light was, before that iconic memory fades.
