I found a never-before discussed NSA document called “Facts and Speculations on ESP and the SIGINT Threat” about poltergeists, Soviet research and PSI phenomenon

https://www.cia.gov/readingroom/docs/NSA-RDP96X00790R000100030013-1.pdf

So when I say never discussed, I mean I cannot find anyone talking about this document online (could be wrong though)

Anyway, it's very interesting… I wonder who the redacted Lt Colonel is?
