I'm reading the second of Ingersoll Lockwood's three books that were "inserted" into our past using the Mandela Effect machinery.

In chapter 17 (17th letter is "Q"), Baron Trump is talking to the Soodopsies, a people who are blind and deaf, and communicate via braille, and "feeling the air movements". The leader towards the end of chapter 17 is describing to Baron Trump how he understands the inhabitants of the world above communicate, amusingly. A neat way of looking at ourselves, from outside.

He mentions that they make noises which then "ventilators" in their heads pick up (i.e., our ears). A few sentences later he says "brain ventilators."

Very soberingly, the children who are being rescued from the "darnkess", some have never seen light before! As in The Matrix, their eyes hurt because they've never "used" them (lights below won't likely be as bright). They will be somewhat "blind" like the Soodopsies. And, due to not having been exposed to many pathogens, their immune systems will be fragile, and they will likely require the use of ventilators.

Ten days, our military will operate in the darkness. Pray. God bless.
