Can the TEW be caused by electronic pest control devices and rodent devices. Can tehy cause permanent damage to human brains and sensitivity? I got bad headaches and it sounded like a quiet radio static coming out of the lights and walls for weeks and other electronic devices like the laptop, cords, and outlets, and even the alarm clock speaker. The static sounds like voices. Even the windows bounced sound voice off the glass. It gives you headaches and causes a dense brain fog. Eventually the EW got so strong like a microwave heat wave on my stomach when I was sleeping and had to move around the apartment. Then one time, there was a strong powerful electronic blast that knocked me to the ground and made it difficult to get back up until i crawled to the bathroom. I believe these are the same devices that affected US workers in Cuba.

Do the creepy voices sound like low-level radio static? It could be from electronic devices used to harass people, pets, and rodents. There are very strong electronic deer devices to get rid of full-sized deer. Imagine that device near a human being that weighs the same as a deer, with the same effects on the brain. They even use electronic devices for crowd control when the police tries to disperse the crowd through non-lethal noises. Check your lawn and neighbors for electronic pest devices or even large powerlines.
