is there any special significance to this phenomenon? I see it quite a bit, but I'm not sure whether it's meant to suggest a reaction, if it's an artifact, or something else.
It can mean a lot of things, but typically it means shock or disbelief. That's why you see it a lot in situations like that or sudden confessions or whatever.
