[TOMT] A story (probably from reddit) about a cannibal who discovers that when he eats someone their spirit lives on inside of him and he can communicate with them.

So he basically suffered from these insatiable urges for human flesh, and he first goes after his neighbour, a young woman, and after a while and a few more victims the voices start to help him with his hunts because if he dies they die with him, and then, when he gets a date it turns out that his date is also a cannibal, as he can see it in her eyes and has voices as well and that's where it ended.
