Let's talk zombie fiction in the form of the movie
Warm Bodies today. There are two types of zombies in Warm Bodies, and neither are your typical brain-dead roamers. First we have what seem like the typical slow-moving, grunt-to-communicate zombies, but via the magic of the voice-over, we find out that there really are thoughts going on inside their heads (or at least in the head of our main character, "R"). However, they've sort of accepted their station and rove around in packs looking for food (aka humans) outside of the airport where they've taken up residence.
When these zombies consume the brains of their victims, they absorb their memories. "R" enjoys eating brains because through these memories, he actually feels more alive. One day his group runs into a group of humans and actually feels the human emotion of attraction for the first time since the zombie apocalypse began. During the fight between R's hoard and the group of humans, he unknowingly kills the boyfriend of Julie (the one that caught his clouded eye), and as he's eating his brain, gets glimpses with her in them.
