The cave scene in Shutter Island....is she talking about MK-Ultra remote control of the brain? (Video embedded)

What if how MK-Ultra works is distracting your chipped brain to pull you into a scenario where you believe you are actively making choices in the real realm when the reality is somebody has taken advantage of this 'distraction scenario' and controls the actual things you do? Is this what she's getting at in Shutter Island?
