The nightmare VR headset is an unremovable object that can only be worn by many players, once the headset was worn, it can no longer get out, almost as if it was glued, or simply stuck to the face of the person using it, as if they were wearing a haunted mask, and also, the codes that used to make everything in the game are hardly simulations, because the nightmare VR headset can trap others into surreal hallucinations, make them come true, and even turn it's own games into reality.
