We've heard about "cognitive changes" from both Covid and the "Vax." I've got an anecdote to share on the latter.
Background: My boyfriend had his first dose of the Pfizer vax way back in May of 2020. Had absolutely no effect. Could have been a placebo for all we know. Since then, he had become somewhat vaccine hesitant, but finally, pressure from vaxxed family members, work, and an upcoming trip to New York coerced him to get the second dose.
Within a hour of receiving the shot, he underwent a remarkable and frightening transformation that lasted about 3 hours. He exhibited what can only be described as profound apathy. In fact, he became a machine with a machine mind. He seemed to feel no emotion other than annoyance at other human beings and what he perceived as their useless and distracting attachments to him.
He deleted multiple friends and family members from Facebook. He refused a call from his brother who he described as "always depressed and suicidal-- it's not my job to keep him alive." That statement was uncharacteristically callous and harsh coming from him. He talked about putting in his two weeks notice at work and complained about all the empty-headed people there being a drain on his mental energy, what with their constant meaningless social chatter.
He wouldn't hardly look at me. He wouldn't let me touch him. He showed no physiological response other than mild agitation. He seemed incapable of human warmth or affection. He talked about just wanting to go somewhere and start over, or "disappear." "With me?" I asked. No response.
It's like suddenly his dopamine and oxytocin receptors had been turned off-- completely. Transhumanism, here we come.
It "cleared up" after a few hours-- but it's left me haunted and confused. Is that all that love and faith and joy and loyalty really are--- just chemicals that can be turned off by an injection? What reason do we have to exist, then? What reason do we have to want or do anything at all? Is this how civilization ends? Everyone just gives up on humanity, walks away, disappears... Existence has become an inconvenience not worth the effort. That is the zeitgeist, right?
Brain damage can cause those kind of changes you described. Take a look at the story of Phineas Gage and see if there are any similarities there.
After the injury changes were noted in his behavior:
Capillary clotting is a known effect caused by the spike protein. One of the doctors who ran D-dimer tests within the limited window of taking the vaccine found clotting in 60% of his patients. That can result in brain damage and organ failure, depending on where the spikes end up.
