Drunk on Death

This is a comedy/horror and yes, I know those two don't usually mix but just bare with me XD

Imagine a world where when you look in the mirror all you see is plain old you, but everyone else sees a monster.
Imagine a world where no on is able to look you in the eye and you have no idea why.
Imagine a world where children run screaming whenever you come round the corner and only one man knows the reason why. And that is the one man, you have been running from your entire life.
Imagine a world where when you are you, everyone dies.
