I must correct you.
When you gave the definition of a real zombie, a posed human being.
They are alive, they don't have control, but from the info you gave us there and then, they're as alive as we are, just in a trance.
No I must correct you;
When we say a Zombie, as in reference to a trance-like state, we mean as a simile.
Example-
God, have you seen Mike today?
He's a zombie...You must define a zombie in EVERY way possible.
And one more question:
How close are games like Resident Evil to studied zombies?
Resident Evil, and the such [New game: Umbrella Choronicles for the Wii], are actually basis for study themselves.
Everywhere there is a different story for how zombies come into being, but most presume the same thing, a chemical of some sort.
Studies on that chemical are inconclusive, but is referred to as
Solanum.
Resident Evil zombies, are fairly close to accurate, in many ways, but rather than compare, we study also.
Once we find out the many different views, we can begin to dissect the loopholes and indescrepencies.
Much like religion.
