Are people who are harboring extraterrestrial microchips they have ingested with food or beverages being programmed by electromagnetic signals coming from their Internet router, appliances, and other devices even during sleep?

This does happen, and this is why it is a good idea to turn off all electronic devices in the home for the sleep interval. At least during that period the person can escape the consequences of exposure and not surrender any useful technology they may have come to depend on for their lifestyle. The best answer is regular healing work done to minimize and reverse any effects on the individual, but minimizing exposure is always the surest and most complete way to minimize the dangers.
