I had a friend that would hear the local 50,000 watt radio station in his head. No one else could hear it. Turned out one of the fillings in his teeth was acting like a crystal radio.
I have stuff like that happen alot. Every now and then my MRC tech 2 turns its self down or up, If I run DCC(not too much since I switched to N scale and havn’t put decoders in everything yet) I would have trains take off on they’re on. Even had a switch that I nailed the points in one position and I came back the next day, the nail was out, the points where the opposite direction, and the train was derailed, Even though I had no power in the building overnight
