Dr. Lalich also references the Heaven’s Gate cult and there’s also a very thorough documentary about that on HBO (https://en.wikipedia.org/wiki/Heaven%27s_Gate:_The_Cult_of_Cults) but (a note from Leslie): This is the stuff of nightmares so watch out if you’re extra-sensitive.
We also talk about QAnon and HBO did a series about that as well: https://www.hbo.com/q-into-the-storm
