What we perceive
Just a little bit ago, I heard a weird sound as I relaxed on the patio with the glass of red, and I looked up and I was unnerved by a hummingbird a few feet away from my face, staring at me. I thought that's some hummingbird with those unusual low frequencies and even ultralow beat frequencies. As I was catatonically staring at the hummer, it suddenly (how else?) exited the scene. The low frequencies remained...another source in the neighborhood. The stature of the hummingbird was a bit diminished, but not the stature of my experience.
