Trying to make a effect where you're screen is wobbled and distorted

I tried to create a effect similar to tarkov’s “Concussion” effect. where you’re screen wobbles and stuff. I tried to see if I could try to replicate it with like a viewport frame and blur effect but it didnt work. Is there anyway I could try to make this?

Have you tried the Blur post processing effect?

Yes, I tried to mix them up but I wanna know how you can make a like, alot of items being cloned at once? i dont know how to explain it.
