What the heck is causing this weird syndrome -

https://en.wikipedia.org/wiki/Havana_syndrome

Some so-called "Targeted Individuals" claimed that they were being zapped by microwave energy weapons. I used to believe they were probably delusional, but after learning about Havana syndrome I'm really not sure now at all. Something extremely nefarious appears to be happening to those poor victims.

What do you guys think is going on? I'd love to hear your ideas...
