Well, if you mean the aspect of mindlessness...the cubicle will do.
But in terms of voodoo, I believe I remember the procedure. It involved the "doctor" applying some medicines containg local herbs but more importantly the venom from a local blowfish that would induce a temporary "dead" state. Then after the funeral, the doctor would find the body and use the person who is then in a state comparable to hypnotic though far more susceptible. Though, I do not know the exact mechanics or anymore details at the moment.
