Many people dismiss witchcraft as stupidity and don't believe it's real.  Some others believe in it but don't have any hypothesis on how it works. I know people who report experiences related to,, for example, "amarres" (bindings) or other effects of those practices, that make me believe that there is something to it. In case witchcraft is a thing,  and not merely a placebo effect, what could be the mechanisms involved? Entities that do the "workings"? Or what? Welcome any thoughts on this
