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?

You can try Raytheon https://en.wikipedia.org/wiki/Active_Denial_System

A notorious local dominatrix revealed many years ago the trick of "burning" her customers with a clothes iron stored in the refrigerator.

How about capsaicin induced pain? That should be very safe as long as you don't go crazy with the most extreme peppers/extractions.

Hypnosis community engages in all sorts of sense creation through hypnosis.

Makes me think of the Dune pain box.

gom jabbar

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.

Mmm, seems like I need to read it a third time. Thanks for pointing that out!
