It is a week nearly, after Halloween or Samhain as it used to be called. At this time of the year we need to be on guard because forces from the other world are at large and liable to come and visit us.
It is the time of the Wild Hunt when the Sidhe are abroad, collecting up the souls of the dead to take back to the land of the dead. There is not much to separate us from the other world at this time and we need to be on our guard and listen for the approach of thundering horses hooves and a loud trumpet call.
You might like to read about the Legend of Sleepy Hollow here. There are many interpretations of this time of misrule.
'Possibly the best known Wild Hunter is the Germanic god Odin and his Furious Host. Usually lame, attended by horses and dogs, he runs through the night collecting the souls of the dead - specifically the dead that were evil-doers in life. Sometimes, instead, Odin is thought to hunt a boar or a wild horse, or even a woman. But Odin was far from the only leader of the hunt. Depending on the country or region, King Arthur, Sir Francis Drake, Gwydion, and even demons were claimed as leaders of the hunt. - Diana Rajchel'
So if you feel you are not alone some dark night soon while you are out walking, it might be best to go indoors and shut your door and turn out your lights...
