Am I Overthinking… or Being Gaslit? | Signs of Gaslighting Explained

The word “gaslighting” actually comes from a creepy psychological trick that started with literal gas-powered lights. In the 1938 play Gas Light (later turned into the 1944 film Gaslight starring Ingrid Bergman), a husband secretly dims the gas lamps in their house… then tells his wife she’s imagining it. The lights flicker. She notices. He denies it. Again and again. He moves objects, hides things, and keeps insisting she’s “crazy” — all to make her doubt her own reality so he can control her.
