Injured/half conscious vision effect

Hi all, probably a strange question, but I’ve seen this effect in lots of games (for instance Call of Duty).
When you get hit by an explosive sometimes you see a multiplied vision effect, and for example when you rotate your camera right and you have a cube in front of you, you see the cube multiplied at the left of the cube, and when you stop moving the camera, the duplicates fade away blurred.

I tought about using post processing blendables, but I’m now sure how could I achieve this with it.
Btw. Sorry for my bad english, it’s not my native language
