He claimed to have suffered from hearing voices and Electro-magnetic microwave exposure.
I experienced a situation in my old apartment.
My neighbor upstairs was using an high-powered electronic pest control device; and because of my fragile health, I had trouble sleeping and started hearing the static noise all the time. It was giving me headaches and I heard random radio voices. I just think there are some humans that are more susceptible to high powered electronic devices, especially if they already suffer from poor health. Prolonged exposure can really make someone paranoid and delusional.
One of my great aunts had a similar problem. She was hearing voices in the house and upon investigating, discovered it was an old radio receiver on the roof or something to that nature.
