I work as a PCT on a locked medical/peds floor. Something happened last night that really creeped me out. My unit is shaped like an H with the nurses station and a couple of med rooms in the middle of two halls of patient rooms. I was working with two nurses, and almost all of our patients had a bed alarm turned on. I was on one side of the hall when a nurse asked me to help her with something on the other side of the hall. We walked past a side door of the nurses station when I saw someone out of the corner of my eye. I thought it was my imagination because I was tired and I rarely work nights. Then the nurse behind me asked me if I saw someone. We checked to see if it was a reflection and then we checked the whole unit. The other nurse had been in a patient's room the whole time and there was no one else on the unit. About half an hour later I was charting in the nurses station alone. As I previously mentioned, my unit is locked. We have a camera outside of the doors, but you can also see into the end of one of the halls where patient rooms are at. The monitor is right next to where I was sitting and I felt an overwhelming need to check the monitor. I look up at it and I see a man walking inside of the unit toward the patient rooms. I only saw him for a few seconds before he faded away. I found both of the nurses working with me, and they had both been in patient rooms on the other end of the unit. I had the same nurse from earlier check the other end of the unit with me, and of course there was no one there. After we checked the unit, I asked the other nurse if anything has happened at that end of the hall recently. She had no idea of what had been going on. She said that a patient passed away down there over the weekend. Apparently it was completely unexpected and rather traumatic for everyone involved. Needless to say, I will not be working another night shift any time soon!
