Mummering traditions in Estonia during St. Martins and St. Catherine's Day.

The mummers are masked characters who go from door to door and bring good luck. Of the formerly rich folk calendar days of mummers, only celebrating St. Martin and St Catherine Day is preserved as living cultural expression, known all over Estonia.
On the eve of St. Martin's Day, 9th of November, people gather together and disguise themselves in unrecognisable form. St. Martins’s day mummers are mostly dressed as men, wearing dark inside-out turned coats, their faces are smeared with soot or covered with a mask. They are noisy and fearsome-looking.
They knock loudly at the door and sing traditional entrance-song in runic verse, describing their long and arduous journey and asking to be let in to the house. The words of the song suggest that the mummers have come to us from some another world. Therefore the mummers are none other than the incarnated souls of our ancestors.

It's like Mexican "Día de Muertos" in some sense
