People, with the knowledge, have the ability from the devil to have "out of body experiences". They can "visit" you in your home or wherever, without you knowing it unless they choose to make themselves visible to you. They also frequently "visit" or spy on you in the form of a black bird or some other animal. A witch personally told me they do this.

Whenever I see a black bird outside through the window, or just several times during the day, I say,

"Father, in the name of Jesus, I cut and burn all the ungodly silver cords." Silver cord is the term they use that connects their body to wherever their "visiting".
