The definition of "Gaslighting" is a form of psychological manipulation in which a person or entity causes someone to question their own reality, memory, judgment, or sanity. The term originates from the 1938 play "Gas Light" and its subsequent film adaptations, where a husband deliberately dims the gas lights in their home while denying any change in lighting, making his wife doubt her own perceptions. https://amzn.to/42YoQGI This content was created in partnership and with the help of Artificial Intelligence AI.
