This is a common problem for alot if TI's...unfortunately it can ruin a persons psych (mind) over time and is very damaging when put upon the victim in the beginning of the campaign..

...especially if the person is a survivor of any abuse. This really screws up any healing they were getting.
In very complicated targeting situations, this will often damage someone who is starting to remember people and things that perpetrators would rather they not.
I have seen that one of the ends that gang stalking is going for is to induce so much damage that a sort of anmesia occurs out of terror or actual brain damage erases memories--permanently.
(This is why people who are stupidly vigilante are useful to the ever deceptive and much smarter, stealth and very expereinced abusers and crime rings of abuse--useful idiots is all they are. They actually HELP destroy a victim who was most likely getting healed or going in that direction or was a threat to perpetrators or an abusive biological family becuz they are dumb enough to believe slander and bad PR campaigns..the real career criminals are sophisticated enough to know who the victims and perps are--this is why crooked law enforcement on all levels is so valuable to crime rings.)
Under less complex circumstances it is simple psych warfare via bad PR campaign. Its terror.
This is one of those things that is so nice to finally see in print so you can feel validated.
