I've followed Ben and Kat Davidson's work at their Suspicious Observers website for more than 10 years, and I love their cosmic view of physical reality. Their THE WORLD GOING CRAZY | Unseen Influences YT looks at how Earth's shifting magnetic field influences human behavior -- I think it's quite relevant to the mass formation psychosis discussion.
