the nightmare comes to earth

Freddy was a poor young college student, was falsely accused of sexual abuse, imprisoned for 5 years until finally dying of injuries in prison, even in his death he was filled with hatred for his fate, after his death he has two options, enter the limbo or returning to earth as a demon, Freddy will return and with him the nightmare will come with him, not just for those who hurt him, but for all of humanity (History will have apocalypse, the MC will get revenge and then increase his powers until finally he puts the land in chaos)
