Trippy stuff, for sure. But the actual Santa-link may be tenuous:

American ethnopharmacologist Scott Hajicek-Dobberstein, researching possible links between religious myths and the red mushroom, notes, "If Santa Claus had but one eye [like Odin], or if magic urine had been a part of his legend, his connection to the Amanita muscaria would be much easier to believe."[131]

Trippy stuff, for sure. But the actual Santa-link may be tenuous:

American ethnopharmacologist Scott Hajicek-Dobberstein, researching possible links between religious myths and the red mushroom, notes, "If Santa Claus had but one eye [like Odin], or if magic urine had been a part of his legend, his connection to the Amanita muscaria would be much easier to believe."[131]

The connection was reported to a much wider audience with an article in the magazine of The Sunday Times in 1980,[132] and New Scientist in 1986.[133] Historian Ronald Hutton has since ruled out the connection;[134] he noted reindeer spirits did not appear in Siberian mythology, shamans did not travel by sleigh, nor did they wear red and white, or climb out of smoke holes in yurt roofs. Finally, American awareness of Siberian shamanism postdated the appearance of much of the folklore around Santa.

OTOH, this vid is discussing the Sámi people of Finland, not the Siberian Evenks or other Easter A-M using shamanistic traditions.

Moore (the first person who seems to mention santa's reindeer-drawn sleigh) drew heavily on the Scandinavian traditions for his jolly old elf.

The mystery continues...
