The subject of this story is a single proton that you would definitely feel if it hit you: https://www.fourmilab.ch/documents/OhMyGodParticle/

I don't think that is the case. The kinetic energy of these super-energetic particles is often compared to a tennis ball. But that energy isn't released at once, so even if it would interact with yourself, that interaction creates a particle shower that takes most of the energy with it. I don't think we can feel one of our atoms getting violently ripped apart.
