My mother claims to have seen a ghost there
She told me not too long ago that she had went with a few friends ( one of which was a security guard there) and they went into Waverly
On the second floor, she said she saw a ghost of a nurse.
The way she described it ( human, but looked like a picture on a fuzzed out tv channel) fits the usual decription
Needless to say, she high tailed it out of there lol
Me personally I'm not afraid of ghosts but I guess you'd have to be in her shoes
