optical and audio cloaking already in use for decades. highly advanced psychotronic deployment already can mass project dreams and detailed holographic simulations either en masse or to an individual. in past eras this was done on a strictly biological bases by a group of three initiators and a single subject (think 'minority report' in reverse). AI being used not only for prediction but non-local communication. subliminal media also added to mass transmissions to add to this effect. enjoy the show. people are about to see the dome. . .think hunger games scene. predictive programming. enjoy the big 'reveal'

The chronovisor was allegedly a functional time viewer described by Father François Brune in his 2002 book Le nouveau mystère du Vatican ("The Vatican’s New Mystery"). Brune is the author of several books on the paranormal and religion.

In the book, Brune relates that the chronovisor was built by Pellegrino Ernetti (1925–1994), an Italian priest and scientist.[1] Although Father Ernetti was a real person, the existence or functionality of the chronovisor has never been confirmed; its alleged capabilities are strongly reminiscent of the fictional time viewer which features in T. L. Sherred's 1947 science fiction novella, E for Effort.[2] https:// en.wikipedia.org/wiki/Chronovisor
