Professor de Pesadelos (2016)

The premise of both surround sketchy people coming to a new highschool. They also try to fix the 'inner school' issues.

Both have a main girl and are in high school and have a fantasy side.
Th drama treat many students cases too but Revenge Note is way more light and cute than Nightmare Teacher

Be careful what you wish for.
That is the theme shared with these two productions. The participants are warned that their requests may have dire consequences. Yet they chose to move forward anyway to feed the need of their basic human desire of instant gratification, revenge, popularity, etc. Both do a great job of highlighting that dark side of human nature.

Both are supernatural, mystery, and school themed. With different main plot, but very alike in many other ways.

School themed supernatural plots, "Whispering Corridors 3" is the most light from the franchise and is a good match to Nightmare Teacher.

Both are better at the supernatural school themed plot - in their own case - then one can imagine.

The main similarity is there's someone/ something killing the students at school.
In The great shaman Ga Doo Shim, the principal has the evil spirit target the lowest ranking student, while in nightmare teacher its the teacher who makes the student disappear

Mystery/Thriller
In Nightmare Teacher, every student has their vices and gets their "lessons" accordingly.

They are both school horror-ish dramas. Both are not scary to the point it scares you however they both give a similar feeling so if you guys liked Nightmare Teacher, I suggest you guys to also try watching "Remember, Hari", it's available in Youtube with Eng Sub under the title

both focus on the desire of highschool students and their complex emotions. i think if you like all of us are dead then nightmare high would be something you'd watch in one day

When i watched the first episode it gave off same vibes, the main characters grant the "wishes "for people and in the witches diner you eat the food in nightmare teacher you have to sign a contract
I recommend nightmare teacher its so good!!!!??

Both series take place in a mysterious and eerie school setting. Both main characters try to uncover the mystery that is in their school and face challenges while solving the problem.In both the dramas the teachers are the villains .In Nightmare teacher they more focus on one or two main characters while in The gifted they focus on each characters of series.

In both the dramas the teachers are the villains ,
in 3nen A gumi hiragi is more of an anti hero, but in nightmare teacher uhm ki joon is the villain.
3 nen is practical but nightmare teacher is supernatural.
but in both the series students are tormented by their teachers, "who tried to teach a lesson "

pretty similar to the fact that it takes place in a high school and there’s a group of students that come together to solve a mystery. In white christmas, a psychologist comes into the high school in this drama, the teacher does but in both cases the students are manipulated into doing things

Even though the two dramas have very different feel to them, they both revolve around the same topic--desire, and how what you want might not be what you think it is.
