Well,we had this strange thing happen with our monitors.It would only happen on quiet nights around 2-3 am,we would be sitting in the nurses station and the central monitor would start alarming,would show ventricular fibrillation (one you shock for) and a strip would print out.It would always be in a room that was fartherest from nurses station but there would be no pt.in that room and the bedside monitor was turned off.It happened several times,always on slow nights.
The older nurses said it was a ghost,I insisted there was a short or some glitch in the system.
After awhile the hospital bought a new more modern system,different brand.I’ll be damned,same thing would happen with the new monitors,same room.

Then one night there was a pt.in that room and around 2-3 am he put on call bell.Went down there and he said a tall woman in long dark dress was standing in corner staring at him,he called out to her but she didn’t answer so he rang. call bell and she disappeared.We thought he was just dreaming,effect from meds,strange place,etc.
Some time later different pt. in that room rang call bell,went down to his room and he related same experience as previous pt.He was somewhat anxious,we convinced him it was a dream,probably effect of meds,strange place,etc.Gave him a Valium and he went back to sleep.We were little shook up ourselves.
Some time later it happened to a third pt.He was almost hysterical and he wan’t buying our explanations.He starting climbing out of bed,said he was going to jerk out his IV and leave.
He finally agreed to stay if we changed him to a different room.Problem is we didn’t have an empty room,we had to swap rooms with a comatose pt.on a vent.That was an ordeal in itself.
Next day the family of the comatose pt.came in and they were irate that their family member was moved in the middle of the night and no one could give them a good explanation as to why it was done.No one wanted to tell them anything about a ghost.
Thankfully,it wasn’t my pt.so I took off.

Shortly after that I got a straight day job elsewhere,never contacted old co- workers to find out if those things continued.

Couple other strange things happened while I was there and heard stories from other nurses around the hospital.
Was kinda hard to deny the existence of ghosts after those experiences.
