How do you term the phenomenon that means
I am feeling it and you are doing it?

For example, when I think of a song,
you sing it. I am willing to believe it's more

than coincidence, but cannot explain its mechanism.
I would like it to be physical—

our bodies' harmonic vibration
on a subatomic level. Something that explains why

I must describe love in terms of shoulder blades,
vertebral hollows, collarbones, & the jaw line.
