Gaslighting is a form of psychological abuse in which false information is presented with the intent of making a victim doubt his or her own memory, perception and sanity. Instances may range simply from the denial by an abuser that previous abusive incidents ever occurred, up to the staging of bizarre events by the abuser with the intention of disorienting the victim. “Gaslighting” is ruthlessly manipulating an individual, for nefarious reasons, into believing that they are going crazy or imagining things.
