Gaslighting
Gaslighting is the term used to describe manipulative behaviour - often adopted by narcissists or self-entitled, self-serving people - that's designed to de-stabilise someone, and leave them questioning their truth and sanity.
The end goal of gas-lighting is to assume power over someone, so you can view the tactics as energy attacks.
This video takes you through a few simple definitions, the signs to watch for, and finishes with some advice in how to deal with (and overcome) gaslighting.
