Not BOO. More like boo hiss.
In my previous apartment there was a week where I was wondering if Casper was messing with me. Pictures in different rooms just started dropping off the walls, not all at once, but always when I was there alone. Then the glass globe over the ceiling light fixture detached and literally floated to the floor in a graceful arc. That was the end of it, although a couple friends offered to provide an exorcism.
I've been in this newer place for three years. Two days ago, while I was doing some bookkeeping, there was a loud popping noise as a large decorative wicker tray dropped off the wall. Ten minutes ago there was a loud bang as a wooden fish-shapped serving tray flew three feet straight out from the wall before dropping to the floor. The nails that held it to the wall are still there, and the piece is still intact.
Given the heavy rightwing presence in this community, I'm thinking I've managed to piss off some republican ghosties. Spooky, but kinda satisfyingly cool. Heh.

I've heard Republican Ghosts love the smell of freedom -- I say it's time for some pachouli mixed with other mind freeing smoke.
