The phrase likely refers to the real-life Smurl family haunting , a well-known alleged paranormal case from the 1980s in West Pittston, Pennsylvania. The Smurl family (Jack and Janet Smurl and their children) claimed their home was plagued by demonic activity, including sightings of a hag-like entity and violent disturbances. The case was investigated by demonologists Ed and Lorraine Warren, who believed three spirits were present — two benign and one malevolent.
"Conjuring" here is probably a loose reference to , since the Warrens’ investigation of the Smurl case inspired elements of The Conjuring 3: The Devil Made Me Do It (2021), though the film primarily focuses on the trial of Arne Cheyenne Johnson. The Smurl haunting is also the subject of the 1991 TV movie The Haunted , based on the family’s experiences. smurl family conjuring
