Cliffs:
- It's a physical experience, not purely mental.
- It's not sleep paralysis.
- 90% estimated do not know they're abductees.
The three pillars, according to Jacobs' research.
1. Inter-generational. If someone is an abductee, almost certainly one of the parents has been one, and their children are likely to be as well.
2. It's global. It's not a just a US phenomena. The earliest case Jacobs mentions took place in 1957 in Brazil. The supposed abductee was
Antônio Vilas-Boas.
3. It's clandestine. They do not want us to know what they're doing.
Jacobs concludes that the phenomena is being done with one of the obvious goals being hybridization. He does not feel, due to the secretive nature of it all, that the end game is "good".
From what I gather there are more than one species of alien involved, although the Greys may be an advanced AI of sorts. The Greys are overseen by a mantid looking race, which Jacobs assumes to be the ones calling the shots. But if you pour over a bunch of cases you'll also encounter stories of The Nordics/Pleiadians which appear human, albeit rather good looking by all accounts.
Interesting stuff from a psychological perspective, even if you do not buy the idea of actual alien abduction, interaction, and visitation. There are tons of stories of supposed abductions to be found on YT for those interested. Please share your thoughts.
