“The idea of “space aliens” from other planets or solar systems has fallen out of vogue.”

Not according to Tucker Carlson, who has contacts in high places. And, spiritual dimensions would not use radioactivity, I don’t think.

This idea of non-alien (i.e., not extraterrestrial) comes from those high places. Folks like Chris Mellon, former Deputy Assistant Secretary of the Army (for Intel), have long eschewed the use of the term "alien" in favor of "interdimensional."

Perhaps the term "spiritual" evokes too much of a religious tone.
