"I had all the characteristics of a human being - flesh, blood, skin, hair - but my depersonalisation was so intense, had gone so deep, that the normal ability to feel compassion had been eradicated, the victim of a slow, purposeful erasure. I was simply imitating reality, the rough resemblance of a human being, with only a dim corner of my mind functioning. Something horrible was happening and yet I couldn’t figure out why - I couldn’t put my finger on it."
Bret Easton Ellis, American Psycho
