Brainwashing

Brainwashing is when someone or something uses special techniques to try and make you change your thoughts, beliefs, or ideas. It often involves repeating something over and over again so that it gets stuck in your brain. For example, a teacher might go over something in math class again and again so that you remember it better. That is one form of brainwashing. But it is usually used in a bad way, like when someone tries to get you to do or think something that you don't want to do or think. They might try to use special words or tricks to make you start believing something else.
