Fear Cage: Coined by TAPS investigators as a nod to Michael Faraday's EMF shield, the term "fear cage" describes an area within a building that is demarcated by unusually high EMFs, creating effects on individuals mistaken for localized paranormal activity. Many who report the sensation of being watched, feeling goose bumps, or experiencing uneasy feelings when entering a specific location in their own homes quite often are victims of this electromagnetic field phenomenon, especially if the fields are targeting the head. Locations where a fear cage may occur typically include sources of high voltage electricity and the surfaces that can conduct them: circuit breakers, 220 voltage outlets, stripped or exposed copper wires, and so on. However, certain appliances (especially older ones) are also commonly responsible for creating fear cages. The most frequent culprits are refrigerators, lighted electric clocks and clock radios, free-standing oscillating fans, bathroom ballasts and ceiling fans, and over-taxed extension cords and power strips. Fear cages caused by appliances are simple to test, since a rearrangement, replacement, or outright removal of the sources should dispel the effect.
