yeah you can say it was a ghost story! lol, I had almost the samething happen, without saying I am crazy, I was in real estate 10 years, I showed this old house one day, got a call someone else wanted to see it so I stayed there waiting, the people had 2 cats, they left them in the basement during showings, anyway I open the basement door and they were standing there hissing with there backs up...All I am saying is I am not crazy but I sense things and I turned around, nothing there but I had a funny feeling like I did at my friends house, turned back around and my necklace was in the floor still fasten, & I didn't hear it hit the floor...
