Hearing Things In DayZ Not There! Am I Crazy? Chickens On Ocean Waves & Zeds Whispering In The Wind! Are the devs messing with us?

Near the ocean I hear the distant clucking of a chicken. When the wind blows I can swear I hear zeds. I know they're not there, but my ears tell me otherwise. Is it just me? Am I crazy? Are the game developers messing with us with subliminal audio clips?
