in order to make themselves and their homes less inviting to these wayward spirits, the ancient celts(凯尔特人)would douse (插入水中, 把弄熄, 弄湿)all their fires. there was also a secondary purpose to this, after extinguishing all their fires, they would re-light them from a common source, the druidic fire that was kept burning at usinach, in the middle of ireland. samhain was considered to be a gateway not only from the land of the dead to the land of the living, but also between summer and fall/winter. for the druids, this was the last gasp (喘息, 气喘)of summer (it was also the celtic new year), so therefore they made sure it went out with a bang before they had to button down (把...弄清楚)for the winter ahead. they would dress up in bizarre costumes and parade through their villages causing destruction in order to scare off any recently departed souls who might be prowling (巡游)for bodies to inhabit, in addition to burning animals and other offerings to the druidic deities(神, 神性). it is also a popular belief that they would burn people who they believed to be possessed, but this has largely been debunked (揭穿, 拆穿假面具, 暴露)as myth.
