At Samhain, the Wicca say farewell to the God even though he readies to be reborn at Yule. This grand sabbat, also known as Feast of the Dead ,Feast of Apples, All Hallows, and of course Halloween, once marked the time of sacrifice. This was the time when animals were slaughtered to ensure food throughout the winter. The God fell as well to ensure our continuing existence. This is a time of reflection and coming to terms with the one thing in life which we have no control - death. Wiccans feel that on this night the separation between the physical and spiritual realities is it's least guarded and it's veil the thinnest.  It is a time for dimensional openings and workings, and also the celebration of the death of the year king. It is a somber holiday, one of dark clothes and thoughts for the dead, it is said to be the  time when those of necromantic talents can speak with the dead and it is certainly a time to remember ones dead. It is a time of endings of relationships and bad situations and it is the time when one can see the glimmer of hope in the future. There are as many concepts attached to this holiday as any other,  truly a time of remembrance of our ancestors and all those who have gone before.
