Zombies, which symbolize something outside the family and in society, are also some bad parts. They are numb, willful, irrational and fanatical. Close contact will make people lose their original self and produce bad changes.
You're afraid, which means you don't like these things and don't want to touch them.
You are not infected by those zombies, which may mean that you are not affected by' zombies' (see the above by yourself), or that you are affected but you don't know (the probability is very small) (it can be understood that your subconscious knows that your brain can think directly but doesn't know).
Only this part = = ... Don't laugh if it's not good ...
