Has anyone experienced witchcraft / incantation used to try and Rip victims heart from chest while they slept?

A woman at church used to be spiritually attacked at night her body would become severly cold her family were scared, confused. They used to call the ambulance/medics round to the house but could not get her conscious at nights. The devil used to take her out of her body to witness evil she described. People think these things are a 'joke'.
