Amazing, I had no idea illusory pain existed. I've actually been looking for a safe way to induce pain, and this seems promising. I would have thought the BDSM community would make use of this, but a quick googling doesn't turn up any products. Any idea why?
The Gom Jabbar was the poisoned needle held at Paul's neck. The box, if I recall, had no name and was only a vehicle for the perceived pain delivered to Paul's hand.
