I have had a lot of strange things happen in my house over the years - lights turning on and off, black shadow figures, music blaring loudly from speakers in the “off” position, smoke alarms and carbon monoxide alarms sounding when the fire department found nothing wrong, car horns sounding continuously until I disconnected the car battery, dishwasher and dryer turning on spontaneously, pets acting terrified for no apparent reason, children with night terrors, myself with apparent sleep paralysis “that old hag” - and no explanation from the (very expensive) electrician I hired to check the wiring or the fire department which investigated the smoke and carbon monoxide alarms. I’m still not sure how to explain it, or what the Orthodox perspective would be, but it seems to have settled since we had our house blessed (by a CEC priest, not Orthodox) and each room sprinkled with holy water. (Actually, my wife had this done - I was more skeptical and kept looking for a physical explanation that I could not find).
