That said, I was using the example of psilocybin merely to illustrate that we have no idea of all the possible explanations of what happened at the Ariel School.
Of course, it may have merely been something as simple as UFOs and grays.
Understood.
While some psychedelics have included flying saucers among their visions I am not familiar with any case where the gray aliens were part of those particular visions.
There have been so many gray alien sightings around the world that we have a detailed knowledge of their characteristics—the large black eyes that seem to communicate visions to humans, the small height, the tiny long fingers, the skin that seems almost artificial or clothes-like, etc etc etc.
I am convinced they are not drug induced hallucinations of any kind.
Terence McKenna has described in great detail aliens seen during drug trips—DMT generates one type of alien, psilocybin another, for example.
