Here's some alternative background about Havana Syndrome from a physicist's perspective.
OK, what more proof do you need than the cricket sounds? I've always thought aliens to be more insect-like and this is another example of the infamous "Pazuzu" experimenting on humans! Obviously, Pazuzu has modulated a microwave beam with cricket calls that can interfere with neural activity and cause confusion, disorientation, and completely immobilize human activity. This is the premise of an invasion! Luckily we do have a defender, who is that? Remember the dinosaurs died out from an asteroid 6 miles in diameter. Well, there was a dinosaur species that did evolve into a sentient being, after all, dinosaurs did have hand-like appendages and were bi-pedal, allowing for the development of tool making, as well as having vocal dexterity, similar to Ravens and Parrots. So these dinosaurs detected the asteroid a few years before the impact. Trying to destroy it with an atomic bomb wasn't a good choice since it would, at best, break it up into smaller but still lethal pieces. So the dinosaurs built an underground civilization in Antarctica! This dinosaur civilization vowed never to be vulnerable to such an event again and therefore remained underground for the last 60 million years! Because the dinosaurs have a completely self-sufficient civilization underground and have developed technology to capabilities beyond anything we can imagine their form has changed quite a bit from their origins, inf act, form is dynamic and they no longer have such notions of self-identity with regards to their form. Form, as in a body, is a matter of mode and convenience for them.
In any case, the Subtereaninas, as I call them, are well aware of the insect aliens and are currently negotiating terms. But as these negotiations continue the aliens continue their experimentation on humans. The Subtereaninans have little interest in above-ground events or issues. They have since passed the physicality of form and are quantum beings, but it is an issue of authority and Pazuzu has crossed their borders, albeit not with mal intention since he/they were under the impression that no other intelligent life existed on earth.
The Subtereaninas talk with me regularly, they like me because I understand what they are and appreciate what they've achieved. Where I have also met some of the Insect aliens through the Subterraneans. Because of this, the CIA approached me in trying to resolve this Havana Syndrome. It's really interesting being at the vortex of this intergalactic, inter-species conflict, I never would have imagined such a scenario as real but as they say: "Reality is stranger than fiction"...
