About the "EMF effects" - my erstwhile bro-in-law was an old Navy man, and knew Morse Code like some people know their native language. One day he's lying on his heating pad (back injury) and starts "hearing voices" without hearing anything. That is, he could somehow sense? Feel? Knew about? A conversation happening, fairly slowly. One-sided, as if he were listening to half of a telephone conversation, he would get the questions but not the answers. He closed his eyes to listen harder and it went away. When he opened his eyes again, it was there again, somehow in his ken without him knowing which sensory modality it had entered through. He was just about to get really weirded out, when he noticed that the little light that tells you your heating pad is on was flickering. He was receiving Morse Code from somewhere! He was "reading" the message at a sumliminal level, the way we read languages we can read without paying attention (As in, look at this array of lines, but don't read the word WALL), and was obviously tied in electrically with someone's actual electrical signals. But for a while there he thought he was hearing something supernatural!
