Another story from the nursing home I work at. In the late summer of 2006 a new resident named Bert came to live there. She was very anxious and became at times very confused. At one time she even got on the phone at the nurse's station and called 911 saying she had been kidnapped.
In spite of her confusion, she was always adamant about her blood pressure being taken right after breakfast. She would not wait for the nurse, but hurry down to the dining room where those who can't feed themselves ate. The nurse was very busy down there so other staff always tried to stop Bert from going down there. She was usually stopped and, after a long talk, she would finally agree to return to her room to wait for the nurse. Many times, instead of going to her room, she would stand near the first resident room on the hall the dining room was on. She would wait there just inside the room until the nurse came back up the hall.
Bert did this almost every day until her sudden (for a person in a nursing home) death. She died about 6 weeks before Christmas 2007.
Sometime later in May of 2008 I was passing ice water on that hallway. As I passed the first room, I glanced in and saw Bert standing there as she had done for so long. She looked just as she did in life: same hair style, same build, same type of clothes she always wore. She was not foggy or misty, she looked just like Bert. My first thought was, "Poor Bert, she is still waiting to have her blood pressure taken."
Of course, when I took a second glance she was gone... I am not sure in her case if this was really a spirit or a type of residual haunting from her doing this so often when she was alive. Since neither I or anyone has seen her since, I am thinking it is just energy from what she used to do.
