Ask her to stop shouting, and if she doesn’t, invest in ear plugs

how will I handle this?
 
just let it happen.

I would happily tell her that she’s supposed to haunt the guy next door.

give her the ice cold stare

I tell her “You made a few lucky guesses, but all your talk about hands and carts that pull themselves wasn’t even the topmost snowflake on the tip of the iceberg. You want to know about humans? How about a deal? I tell you all about humans, show you all our history and what may be our future. I’ll even mourn your passing. Ghosts like that, right? In exchange, you shut the hell up and maybe use your ghost/magic abilities to help me on occasion.” If she goes for it, excellent, let me teach you about a thing called “The Simpsons”. If not, I build an atomic suckulator.

Yes, Lyra, you were right…
 
Damn insufferable unicorns.

@ze  
I wouldn’t say they’re paranormal “experts”…

“So like, if I avenge your death or make out with you or something will that complete whatever unfinished business you have binding you to this reality?”

YES, YOU WERE RIGHT ALL ALONG ABOUT US! NOW STOP SCREAMING, IT’S 4 IN THE BLOODY MORNING!

If I can’t convince her to stop screaming, I’d do my best to ignore her. It’s not as if she was having any other effect on the world.

earplugs.

Who yah gonna call?  

 
>Not even paranormal experts  
Oh god damn it.

Compliment her on her almost supermodel-like figure. Maybe feed her some other dead things to put some meat back on her bones. I could deal with the screaming if she was cloppable, but I’m not into skeletons.

Id go insane.  
Then I go talk with Pinkie.

Feed her ego, admit that she was right and all the fun of throwing it back in our face goes away.

Ignore her.

GHOST BLOWJOB! WOOOOO! WOOOOO!

If I can talk to her, I’d try to calm her down.  
If I can’t, I’d see some psychiatrist.  
If it’s no use, I’d just end my life.

I’d be fine with it

Who ya gonna call???
 
GHOSTBUSTERS!!!

I didn’t put that in my psyche  

Tell her to stop. And have a chat with her everyday.
