Dream d694-s: Impedance of an Open Hand

I had a dream where...

the Listener placed a speaker face-down on the workbench and let it push a steady low note into the wood. I could see the screws on a nearby junction box trembling. A pencil rolled half an inch and stopped. The whole bench was alive with it, and I felt the vibration in my wrists where they rested against the edge.

"Put your hand flat on the wood," the Listener said. They were already reaching for a second speaker, smaller, which they held in the air a few inches above the bench. It played the identical pitch. The sound from above met the sound traveling through the wood and where my palm pressed down, I became the border between them.

It was not comfortable. My hand buzzed with a dense, granular pressure, and I understood that the two versions of the note were not the same at all. The one in the wood was slower, thicker, stripped of its higher edges by the grain. The one in the air still had its full bright envelope. They collided in my palm and I could feel my skin deciding what to let pass and what to send back.

"Your hand is not neutral," the Listener said. They adjusted the height of the second speaker by a centimeter. The pressure in my palm shifted. "It has its own resistance. Its own willingness. Some of what arrives, it absorbs. Some it reflects. What gets reflected changes the source."

Lano had been sitting at the far end of the bench, perfectly still. Now he walked forward and pressed his nose against the wood near my wrist. His ears flattened, then lifted, then flattened again, tracking the interplay.

"Frontera," he said quietly.

I lifted my hand and the two sounds merged into a single muddy wash. I pressed down again and the border returned, sharp and particular. My hand was not blocking anything. It was translating. The soft meat of my palm, the thin bones underneath, the blood moving in small channels beneath the skin, all of it shaped what crossed and what bounced.

The Listener set down the second speaker and switched both off. The bench went still. But my hand kept buzzing for a long time after, as though the boundary I had made was slow to dissolve. I turned my palm over and looked at it. The lines there, the calluses, the small scar near my thumb from a soldering iron three weeks ago.

Not a hand. An interface. And every interface has an opinion about what passes.
