 Gaslighting is a psychologically manipulative tactic when someone gets you to question your own reality, your memories, your perceptions. I believe that autistic people are much more likely to fall for this kind of manipulation. This may be due to our inherent difficulties of understanding indirect communication and focusing primarily on people's words rather than the context and the way that people say them. Personally, I find gaslighting to be the most disruptive thing to me when it's centered around my autism. It will tell you that you do not understand these complex social things in order to gain the upper hand. Although you do have that insight and understanding, that will play on your insecurities. Make sure that you look out for this kind of behaviour because this is not right. Especially if you know that you understand the situation, you are a human being, it doesn't matter if you are autistic or not, you need to stick up for yourself.
