Thats interesting, the Norse folklore has a lot of these stories. They leave fun or gifts to lure the unsuspecting? Or, do they just want to keep alive the ritual of the mushroom and hide it in stories?
There are many references to those red capped folklore, that might point to a certain type of mushroom, which was poisonous and psychadelic and maybe made you hallucinate giants or reindeer flying.
Fascinating stuff. Nothing is free.
St Nicholas is red and white symbolizing certain poisonous but magic mushrooms.
The reindeer were forced to eat the poisonous mushrooms and their livers took the poisons out, and then they smoked the reindeer droppings and went on psychadelic trips to 'other' worlds to experience those other dimensions and realities where reindeer flew around with Santa and Rudolphs red nose lead them. Messages in there passed down in childrens stories.
And, why did they always tell these to children in stories, which makes this extra nepharious.
I think the message is, gifts always come with strings, you MUST offer something in return if you accept a gift from one of these, and its best NOT to accept them at all.
But it is why children offer Santa a gift of milk and cookies. If you get a gift and don't, then, you will owe this jealous trickster and he will come back to get you.
What does he fill stockings with, ie, leave gifts in your place maybe and take your spirit away?
Children, always remember to leave a gift of milk and cookies or a gift to exchange, since mischievous beings like elves, odin, Santa, Nisse, gnomes, they don't gift for nothing.
Or, just say no. lol.
