Shaman Khalid Mohamad went into a trance during a ritual in the Malaysian jungle where Nora disappeared 10 days ago.
He said he believes the spirit – which can take on human or animal form – was attracted to the 15-year-old because she has special needs.
He said: “Tonight I will ask for the spirit to return her… but they will ask for something in exchange.
“That will be between me and them. Most important now, the child will be released.”
Nora vanished from a hotel in southern Negeri Sembilan state and a £10,000 reward has been donated by an anonymous Belfast business to help find her.
Parents Sebastien and Meabh, of London, said: “She is so precious to us and our hearts are breaking”
About 350 are searching for Nora and police are using dogs trained in finding dead bodies.
But a member of the search team said: “As of yet the dogs have not found anything and that is a good sign.”
