Do household sources of extraterrestrial programming include cell phone microwave signals, some appliances that are switched off, or even house wiring electrical current flowing through lighting, alarm clocks, etc?

As you have seen, intuitively, all of these sources are capable of sending messages by activating the various types of microchips that are routinely present in food and beverages from commercial sources. There is no way to escape—other than going to a remote wilderness area that is not covered by remote satellite technology, as yet. This, in the future, will also prove to be impossible with the blanketing of the globe that is envisioned, and specifically for that purpose, to leave no room for escape, anywhere, from the reach of the Extraterrestrial Alliance.
