is according to Finnish folklore, a "reflection" which goes ahead of each person. For example: you can see etiäinen coming home as your spouse and walking into kitchen. When you take a better look, the whole sight is gone. In a few minutes the front door opens and your spouse comes home and walks into kitchen, this time for real. So, etiäinen does the same things in advance as real humans do a little bit later. Every one of us has their own etiäinen, gotten when three days old – some have stronger, some weaker.
