The voices are real, Gentlemen. You can try to eradicate them, but they still exist.
The voices who speak to us. First you took the voices from the outside and put them on the inside and called them the subconscious. Then when you heard them again you called them psychosis, and you killed them with your poison. One hundred and twenty people you killed, and the day after, you built a mental institution on top of the mass grave--so that when one hears the voices of the spirits, you can condemn him as a madman.
