Perception Altering

Perception Altering is the ability to control, alter or induce effects up other being's perceptions.

A substantial amount of profuse torture can alter one's view of reality.

Currently, Sam, with the 'wall' broken in his head, is having intense hallucinations of Lucifer, which has gotten to the point where he starting to be amenable to the Devil's commands.
