FBI declassified document

[Sinera]

was that an actual FBI site? looks fake and click-bait-ish to me

Seems legit to me. This https://vault.fbi.gov/ has also this as a link to the main FBI site https://www.fbi.gov/

The first link was "just" an article on the document and topic. It's from a normal site of the metaphysical / alternative internet community http://www.collective-evolution.com/ , I like it as they have a range of topics. Of course, you can find other articles on this document on the web.
