A general conundrum for the Khmu of northern Laos is the persistent unknowability of spirits. The locals gauge the potency of spirits by keeping track of spirit stories. Spirit narratives can be conceived of as transient traces of intangible spirit phenomena, as will be exemplified by the story of a young man’s spirit affliction. Sharing and silencing spirit stories are a means of determining the strength of spirits, as well as an efficacious way to evoke them. Using works that embark from the fragmentary and experiential character of animist cosmologies, it will be shown that approaching spirit stories as traces of spirits will be a suitable way to address the perspectives of those who navigate a world that is not inhabited by humans alone.
