When thinking of light moving, don't even think of it as individual photons. Instead, it's a probabilistic wave function, with energy corresponding to one photon and which evolves according to all possible interactions it might have.

As long as the wavefunction interacts with something that is not connected to you, it continues to evolve in its strange quantum way, possibly extending its probabilistic state to other objects. We then call it entanglement.

Finally, that wavefunction will interact with something connected to you (your eye, your detector...) and at that point, we say that wavefunction collapsed and you can count it as a photon. But before that - the only significance of "photon" is that total energy of the function was one photon.

It is actually a little bit of evolutionary fluke that, in us, the electrical path from one hand to the other hand goes directly through our heart.

As a result, electricity is far more dangerous to us than to life in general.
