Calling cards

[Friday The 13th]

Ahhhhhhh, here's one. Well, it's kinda broad, but zombies moaning. Any book, or movie where slow moving (or sometimes fast) zombies are trying to get ya, the moan usually meets ya before the hoard, and in World War Z and the Zombie Survival Guide it states that the constant moaning can drive people who have been under siege by the living dead insane, or the sieged can start to make lots of mistakes in the stake of their survival.:zomby::zombie:

This reminds me, I just finished reading some of that book!
