You've had the ability to see spirits for a while, and it's been tormenting you everyday to try to pretend they don't exist. Seeing their disfigured bodies as they wander has been etched into your mind. You've grown used to seeing monstrosities until one day you see one that looks normal.. but you're unsure if you can trust it so as usual you ignore it

Suddenly he walks up behind you, looking over your shoulder as you try to pretend it's not there

"Hm. Hi there"
