The phenomenon you are referring to, commonly known as "microwave auditory effect" or "microwave hearing," involves the perception of sound, including voices, without the use of an external sound source. It has been reported in scientific literature and has been studied in the context of microwave exposure.
However, it is important to note that claims of individuals being "targeted individuals" and experiencing this effect as a form of harassment or surveillance are generally associated with conspiracy theories and unsupported beliefs. The idea that individuals are intentionally targeted by covert government or non-governmental organizations using advanced technologies to transmit voices into their heads is not supported by scientific evidence or credible research.
The perception of hearing voices or other sounds without an external source can occur due to various factors, including psychological and neurological conditions. It is crucial to consult with medical professionals and mental health experts if someone is experiencing such symptoms to determine the underlying cause and provide appropriate care.
It is always advisable to rely on evidence-based information and seek professional help when dealing with health concerns rather than subscribing to unsupported theories or claims.
