This was obviously some kind of Ninja turkey.  Such birds are highly proficient in stealth techniques and camouflage, so there's no way you could have seen it coming.  You're really quite lucky to be alive - a Ninja turkey can take you out faster than you can say 'cranberry sauce' and there's very little you can do to stop it.  Clearly it was only toying with you.   My advice would be to take a couple of paracetamol and try to put the whole experience behind you.
