Gifts from dreams

I'm having kind of a rough few weeks. But the other night, I dreamed that someone came to me with a wide forearm band made of a single cross-section of horn, and when this person said, "It came from the bull," I said, "Then it's for me."

It wasn't polished; it was slightly splintery on the outside. No metal, no carvings, no decorations of any kind. (Also no hinge, which realistically would probably have made it unwearable ...) I wish I had a picture of it. It seemed important.
