Nic Pizzolatto a déjà évoqué les hallucination de Cohle :
The show is straddling a fine line between realistic terror and what could be interpreted as the supernatural, or figments of madness. Do you find this a tricky balance to pull off?
Nic: A bit. We have a hallucinating detective in episode 2, which is weird, and the visions themselves are almost religious in their metaphysical nature. But the important thing, I think, is that there is a realistic explanation for everything. Cohle’s visions are accounted for by his neural damage, probably guided in some part by his unconscious associations. There’s no evidence to suggest that the things we’ve seen are the result of anything supernatural. Ritualism, some sort of worship is implied in the murder, but there’s nothing supernatural. Reality is the dread, and that’s probably where the line’s drawn. So we can touch these things and by doing so provide avenues for layers of meaning to settle and refract and resonate, but we don’t strictly-speaking break from the realist mode.

Et il vient de lâcher des info sur la saison 2 :
"Okay. This is really early, but I'll tell you (it's about) hard women, bad men and the secret occult history of the United States transportation system,"
