do you believe in ghosts?

[Duchess]

Someone died in one of the apt. above the main stable & on a few different occasions I've experienced something that couldn't be explained...

...I was in Cowboy's office & it's all windows, the back wall is glass & it looks out upon the horse pool and the sides look out upon 2 wings of the barn, I thought I was alone but I could see the shadow of someone working in one of the stalls, the reality is I WAS alone, I've also heard the sound of someone walking around the pool deck and there is no one there.

I know what I saw & heard but I hesitate to call it a ghost even though I can't explain it.
