Where women, who are NOT allies for other women and the vulnerable, psychologically manipulate others, causing them to doubt their own experience/ their own sanity. Ghislighting is how a predator's female ally explains the predator's words and/or behaviors as if they are not REALLY what the victim experienced. To deny another woman's felt experience as untrue, exaggerated, mistaken, etc, out of warped loyalty to the beast of prey. Pronounced geeslight, geelighting, geelighted.
Until she realized that she was being ghislight (ed) by her sister-in-law, she had lost all trust in her own experiences in the marriage.
