Cuban communist regime uses BCI to control the Cuban people
My name is Juan Manuel Castellanos Hernández, and I am a Cuban and Spanish citizen. I was born in Cienfuegos and lived in Cuba until I was 33 years old. Currently, I am 36 years old and I live in Barcelona, Spain.
I want to publicly denounce the use of military technology by the tyrannical communist regime in Cuba, which is being used against the Cuban people. This is the BCI (Brain-Computer Interface), a technology that allows direct control of a person's brain. With this technology, it is possible to manipulate all aspects of brain function, from inputting thoughts to controlling physical movements, all wirelessly.
Brain-computer interfaces (BCI) are systems that establish direct communication between the brain and a computer. While similar civilian technologies exist, such as Neuralink, I do not know the specific technical details of the military version used by the communists in Cuba. It is important to note that military technology usually has a considerable advance compared to civilian technology, with development periods that can span years and even decades.
My statement is based on my personal experience: I was connected to this technology in Cuba in 2021 and continue to be so to this day. I have been subjected to torture using this technology, including the constant bombardment of my brain with messages and thoughts. I have been deprived of sleep and all my senses have been attacked, in addition to controlling my body and causing me intense physical pain.
Cuba is on the list of “terrorist-sponsoring” countries of the United States of America. The Cuban regime has committed systematic human rights violations, including arbitrary detentions, abusive criminal proceedings and torture. They have murdered opponents and sunk boats. The purpose of this technology is clear: control the Cuban population, quell any attempt at a popular uprising in search of freedom and, with impunity, torture those who oppose the regime.
I have gone to the hospital in an attempt to use the BCI as evidence to show the world what is happening in my brain and obtain evidence of the torture I have been subjected to. It is a perfect alibi, but I still make the complaint in the hope that some intelligence agency will support my testimony, since I know that they are aware of the existence of this technology and the abuses that are being committed with it.
Update (August 2026, Colombia): Freedom
After years of torture, with no hope that freedom would ever arrive, I suddenly receive it. I have gained much more autonomy and the voices fall silent in my brain. It was the arrival of a new government in Colombia, something my mind was not able to process as a hope for change.
I cannot say for certain how it all happened, but, apparently, Raúl Castro, Pedro Sánchez and Gustavo Petro —all from corrupt, left-wing governments— took part in the infamous tortures I have suffered all this time under the orders of the Castros in Cuba. I must clarify that I have no proof other than the change in my situation. In 2021, upon my arrival in Colombia for two months, I also received freedom, but I was expelled from the country; between Cuba and Spain, I chose the latter.
This leads me to theorize (again, I clarify: I have no proof) that this is a technology handled by States and that, for some reason, it has been kept hidden from humanity.
I do not believe that the complaint I am making will bring about a great change, since it is very hard to believe. Even so, I have received warnings in my brain not to tell what is happening to me. I have no other choice: if I do not make the complaint, I am complicit in the evil that is being done, and by making it, I am informed that they can keep torturing me so that the powers of this world are not exposed.
For now I enjoy much more freedom; pray for me and for humanity. It is wise now to advocate for neurorights. Believe me, this is not a problem for tomorrow; Havana Syndrome proves it.
