I have one relative who is especially bad about gas-lighting, whether she does it on purpose or not. I think she does given I’ve been victim to it several times. The moment you do something that doesn’t suite her preference or version of things or you refuse to clean up some mess she’s created, she’ll rewrite the events and tailors them to paint the other person in a very poor light, even when she is in the complete wrong and the person she’s besmirching is the actual victim. I’ve since cut ties with this person because as kind as she pretends to be, she’s absolutely toxic.
