This sharing is one my father did. In his last week at the bank where he had bin working for thirty years, where after he would finally retire, two events happened to him which were of the ghostly nature.
On monday he was standing up at his desk looking down on some papers when suddenly he felt how something hit his back. As he turned he saw one of his colleagues staring at the coat hanger laying at his feet.
"Why did you do this?" he asked him. "You will not believe me." said the man "but that coat hanger lifted up from the chair here, and flew out of its own through the air hitting your back!" And as the man was far removed from the particular chair and showed to be truthfully startled, my father, who is open to the super natural, believed him.
Then on friday there was a farewell speech being held in one of the banks halls. Several members of higher rank, from of the balcony, came to thank the staff for their many years of loyal service. And as it was a woman's turn to talk, my father noticed how behind her another woman appeared. A transparent Lady who started rising up until she was hanging above her head. She seemed to be amazed while she gazed over the crowd. Then she moved towards the ceiling and vanished into it.
The Lady wore an early 1900's dress.
We always thought these two events were related since they took place in the same week.
