The idea of being way out on the open water, and pulling up your anchor and finding that it is bringing up some giant steel-wrapped black cable up out into view

The idea of being way out on the open water, and pulling up your anchor and finding that it is bringing up some giant steel-wrapped black cable up out into view as you look over the edge of your boat, going off in either direction downward into the seemingly infinite deep water... brings up some crazy weird primal fear [1] in me. I wouldn't even want to touch it, let alone haul the cable onboard and cut it. I'd cut loose the anchor chain and hope to see the thing again.
