In Finnish folklore, all places and things, and also human beings, have a haltija (a genius, guardian spirit) of their own.
When the person finally comes home, they would repeat the actions of their etiäinen that the people waiting witnessed earlier.
[1] In modern Finnish, the term has detached from its shamanistic origins and refers to premonition.
Unlike clairvoyance, divination, and similar practices, etiäiset (plural) are spontaneous and can't be induced.
As these phenomena are still reported today, they can be considered a living tradition, as a way to explain the psychological experience of premonition.
