Examples of Delusions of ControlBelieving that thoughts that are not your own have been placed in your mind by an external sourceA 29-year-old housewife said, “I look out of the window and I think the garden looks nice and the grass looks cool, but the thoughts of Eamonn Andrews come into my mind. There are no other thoughts there, only his… He treats my mind like a screen and flashes his thoughts on it like you flash a picture.”
Examples of Delusions of ControlBelieving that your behavior is controlled by an external forceA 29-year-old shorthand typist described her (simplest) actions as follows: “When I reach my hand for the comb it is my hand and arm which move, and my fingers pick up the pen, but I don’t control them… I sit there watching them move, and they are quite independent, what they do is nothing to do with me… I am just a puppet who is manipulated by cosmic strings. When the strings are pulled my body moves and I cannot prevent it.”
