Instract

Although hypnosis is a science, it can easily become a tool to control or hurt others when it is not used correctly or have selfish thoughts.

For example, now the hypnotist hints at you in hypnosis that when you wake up, as soon as you see him touching your nose with your hand, you have to open the window.

Then when you get rid of hypnosis and wake up, you may chat with friends in your room, but as soon as you see the hypnotist touching your nose, you can't help going to the window and open the window! So, what if he didn't ask you to open the window, but... kill people?!

In ancient times, there was a saying that the dementor bell is magical in our modern view. In fact, if you have really experienced hypnosis in modern times, you will find that the bell is just a hint like wiping your nose. The difference is that this hint is changed from action to sound.
