This is the incident that Ron called Fac 1 (Facsimile One, the first whole track implant that Ron found in 1952). There is some description of it in History of Man and more on the HCL lectures as well as a demo session of running somebody through it.
But this was being run before we had the idea of finding the implant items or new very much about implants. The demo session consists of a PC trying to run through the first moment of impact with Dianetics and mostly consists of her sitting there and moaning miserably for about an hour until she comes up to feeling better about being hit by the first "bap" (wave impact) coming from the implant device (a coffee grinder - black box with a crank).
The implant was commonly used around 1-2 million years ago in this universe. The Disney movie "The Black Hole" has a lot of scenery appropriate to Fac 1, uses an implant device that is almost correct, and illustrates a starship crew that look like they have been regularly implanted with Fac 1. If you subtract out the cutsey-poo Earth people, you wouldn't be too far off.
This is a third invader force mockup. The ship's captains were the only aware thetans. They look a bit like people wearing space suits, but that was actually their bodies. The crews and troops were so heavily implanted that nobody even remembers being part of the third invader.
When they took over a planet, they would set up temples and appoint priests and give them portable (tripod mounted) Fac 1 implant machines (coffee grinders). Their avowed mission was to make people good.
This could be called the pleasure/pain implant.
The items alternate between things they don't want you to do which have a heavy wave of pain and the opposite which has a heavy wave of pleasure (almost sexual).
They aim the device at various spots and run the entire series of items in each of the points. The usual sequence is:
1. Forehead (third eye)
2. Left eye
3. Right eye
4. mouth
5. left shoulder
6. right shoulder
7. chest
8. stomach
9. genitals
The items are as follows. You need to spot the intense pain or pleasure wave hitting you along with the item.
1a. (pain) To Be Everything 1b. (pleasure) To Be Nothing
2a. (pain) To Know 2b. (pleasure) To Not Know
3a. (pain) To be Oriented 3b. (pleasure) To be Disoriented
