There is one who is real.

All the others are his imagination.

Everything that surrounds the real one is fake and imaginary.

The fake and imaginary people may show emotions, confusion. They may say that they are real, but this is part of the theater. They are just trying to hide the secret about the real one from reaching the real one.

The real one was publicly executed and humiliated, had a severe trauma and is now in a coma. Imagining all this fake life for him, in order to forget the trauma.
