Thank goodness something like that's never happened to me mr Papper! I've seen shadows hovering over me a couple of times on waking up, funnily enough I was not afraid and would go right back to sleep. This happened each time I lost close family members unexpectedly; my dad, 2 brothers and my dearest uncle who was more like a brother to me. My dearest sweetest uncle whose tragic story I will share one day, when I'm ready, often had encounters with restless spirits, very disturbing of course.
One story he told, was about their neighbour, an elderly lady who suddenly out of character used to call him to the fence every afternoon when they would have long chats. This went on for about a week. She fell ill and was taken to hospital. Apparently he became extremely agitated one evening for no reason, went to his room and the neighbour's face appeared, he said it was like there was a haze around her. Of course granny and his sisters had quite a job calming him down and said he must have imagined it. A little later they received a call from the hospital (the neighbours did not have a telephone), the old lady had just passed away!
But I do agree with @simplylizelle, when bad things happen in a place, I do believe bad vibes get trapped and the place needs a thorough cleansing physically and spiritually. Well that's my belief in any case! I'm such a ninny, would not want to stay in room 111 ever mr Papper!
