https://www.youtube.com/watch?v=4OZid6Yl3O8 it first mentions this glyph then at 5 minutes it brakes down and explains the glyph. It's best to start at 5 minutes.

This is a really good documentary, it's NOT the "DMT: the spirit molecule" you think it is, this is an actual documentary, which happens to have nearly the same title, but is vastly different regarding content...
Any way, finding the location of this glyph is the goal, it appears to be in a museum of some sort judging by the film, which means I should be able to locate an actual picture of the glyph...
