The Uncanny Resemblence
The zombies that we see in films and in popular tv shows are vary similar looking to normal human beings. Some times in these tv shows and films people mistake humans for zombies because of how familiar they can seem. Some zombies appearances might not be quite the same as humans, however their actions sometimes mimics human actions. People that have a certain routine they perform every morning or throughout their day at work is similar to what zombies do. Zombies wonder around aimlessly not thinking about what they are doing next because they don't have anything else to do but wander. People who do the same thing at their work place have a similar process that they do everyday acting like zombies aimlessly drifting through life not enjoying it much like a zombie.
