I have devised an evil plan.
One of my teachers is absolutely horrible, the kind of witch that literally everyone including other teachers hate. She's verbally aggressive, arrogant and generally acts in a really despisable manner.
During her class, she always puts the same playlist in spotify, with the volume turned down. I have acquired the link to this playlist and saved it.
Now, over the last months they have been exposed to this teacher and the music at the same time, so I think they must have developed some kind of psychological link between the two.
Also, keep in mind that a continuous tone played at around 17kHz or 18kHz played within a certain dB range can be very hard to hear, but SUPER annoying.

Here's the plan: During lunch break, I'm gonna put my headphones on and play the 18khz sound long enough to make them uncomfortable. Then, I'll start doing my assignments for that teacher and play that music. It's only a matter of time until they begin bitching about the teacher.

I love fucking with people's minds, if you guys know other psychology stuff that can be used to manipulate or stress people, do share.
