When I was about fourteen, my mother worked at a small hospital as a registered nurse. Over the course of a few months, six or seven hospital employees, the doctors & nurses, had loved ones either die or become seriously injured. One's daughter was killed in a car accident, another's husband abruptly died of pneumonia, another's husband committed suicide. Nothing was happening to anyone who worked there, just people they knew. It seemed like every other day my mom would come home with some more grim news. She said people there got scared whenever the phone would ring, dreading the latest. It actually scared the hell out of me, I was worried something would happen to me. Thankfully, nothing ever did.
Also, my mom said a few people had thought the hospital was haunted. Someone heard breathing right behind their neck, a few people felt like they were being watched, a room call button would go off with no one in there etc etc. .
Edit: Talked to my about it & she cleared some things up I was foggy about.
