We had something happened where I used to work. There was a hallway with three rooms for isolation cases, 2 positive pressure, one negative pressure at the end of the hall. For the sake of explaining, 71 was first by the nursing station, then 72 in the middle, and 73 was at the end of the hall, the negative pressure room.
Patient in 71 was a Walkie-Talkie, fully lucid up until then. She starts ringing us at like 3am, telling us that the gentleman from down the hall keeps walking past her room. She knows he is not allowed to be out of his room, so is concerned and wants us to check on him.
The problem is that this man is pretty much bed-bound. We quickly go check on him, and it turns out he passed between our last hourly rounds and the time this woman spotted him walking by. Patient could not be resuscitated by then.
Also had another event, not quite anything about hauntings, but was definitely freaky.
At change of shift, I come on the floor to find everyone working on a code. They had been trying to bring this lady back for around half an hour, but she had many co-morbidities and we all had little hope. Finally, the MD decides to call it. As everyone starts walking away, the nurse at bedside is taking off all cuffs and monitors. She then calls out "Hey, she just breathed!" Keep in mind, no breathing or heartbeat for around half an hour now, had been getting bagged and had chest compressions and all. So the MD tells her not to worry, that expiration is normal since the body is just expelling air. Nurse answers, "No, she breathed IN!". So everyone rushes back in, start working on her, and indeed, she was 'back'.
Now of course, with my twisted nursing sense of humor, all I could think of was that scene in Dawn of the Dead when that obese lady dies and comes back after everyone has turned their backs on her. No one understood the reference
. But until the time when she got transferred to ICU, I just kept expecting her to sit up in bed like that woman in the movie lol.
