Have you heard of such a thing as mega death?
I never heard of it.
Apparently, STS use some sophisticated punishment for disobedience.
Probably, they can punish many ways using our programs and manipulating the body chemicals. Ex: abducting and putting trigger mechanisms Laura mentioned in Wave series. But, that is one in body.
It involves the soul being repeatedly reincarnated into a clone of its body and subjected to torture.
I don't think 4D STS has any control over who reincarnates in which body. They can program people in 3D, if the program has very LASTING effect on them, that individual soul may choose to be born according to their free will. BUT, once soul is in 5D, they have SO much opportunity to see the drama, they can EASILY choose NOT to reincarnate. there is nothing 4D STS can do.
This is possible because a soul that has not entered the tunnel with light at the end can be practically indefinitely incorporated into a new clone of its body.
That is possible, if soul didn't go to 5D and hang around in 3D "neighborhood" ( I mean real "Ghosts" not soul imprint iterations) out of ignorance. But, there are many "means" 5D "relatives" can intervene and try help the situation.
I read some cases, where 3D living person is adducted and soul is moved to the physical bodies of incubating "hybrids" for torturing and programming purpose. But, those cases very small I think. Recently C's mentioned that these hybrids are only few millions. That is a small number compared with world population.
STS beings use this clever incarnation method to bypass the spiritual fifth density they detest.
I don't think that is so easy. 4D doesn't want 3D body as 3D is very limiting. In 4D, they have variable physicality, so I guess they can rejuvenate the body. But, that also needs LOT of energy from some where ( suffering from 3D as their connection to 7D is severed because of their intense entropy). At the end 4D STS also has 5D soul, it is their 5D soul decision that dictate whether go to 5D or not. Interestingly, C's mentioned 4D STS life span as 800 to 2000 earth life years. So, I guess there is a mechanism to limit all these methods.
Unfortunately, they also came up with an idea on how to torture in this way.
torture can take many forms - physical, mental, emotional etc. as long the person chose to be ignorant or not asking for help.
