Okay, so I have a world just like ours, except all the myths are real. Maybe. The Masquerade is in full effect - there is no such thing as monsters and you'd be crazy to say otherwise. This is vastly helped by the fact that most monsters either look like humans or hide fairly effectively. There is also a small government branch that helps with ID and all that if you're a law-abiding monster (and sends hunters if not).
Of course, no disguise is 100% foolproof, so you occasionally need excuses. A Vampire might claim having migraines to explain their need to stay out of the sun, or anemia for their pale skin and need for regular blood donations.
Werewolves might actually go with a fake disease like Lycanthropy and just claim the doctor who discovered it thought it was funny because the symptoms match so well (eyeroll). Hormone imbalance linked to moon phases and all that, gets really painful with cramps and seizures... children sometimes suffer hallucinations, too. Explains everything.
I'm kinda stuck on what to do with my ghosts, though. Depending on their strength, they are either invisible unless you know how to look, or they look like regular people. There is some in between, but for the sake of the question, let's assume the ghost is powerful enough to look fully human. Visible, tangible, smells mostly human (some incense, too), even his shadow and reflection align, he's breathing and has a pulse. Assuming he fakes all of that well enough, the only thing that betrays him is the light behind his pupils - so faint you can't see it unless it's really dark, but it flares badly on camera. Everyone has cameras nowadays. Another problem is that the ghost can only leave his haunted house for a limited time. How long varies with how much energy he has - he might go on a lengthy vacation one time, or be stuck indoors for months at other times. His comfortable average is three to six hours a day, which is little time to get a job if you look young and healthy enough to work fulltime.
So, in short:
1.) How does the ghost prevent being exposed when he mustn't be caught on camera with his eyes open?
2.) What (medical?) condition could explain his inability to work full-time/ leave the house at times?
