Sir I took some of Nightmares files and made one for Psycho now that we know that he was in control.
Psycho File- we know his first appearance was after Nightmare fell into the temple and seamlessly survived the trap explosion. We believe this to be psychos work in saving the new host as the revival book. It seems that he has caused all the crimes nightmare was thought to have done.
As of right now we don't know much but more will be added soon.
