This is what happened to my father.
He worked for the gas company and he and 3 others were laying some pipes at the Holy Trinity Church, Micklegate, here in York.

It came to lunch time but the job was not quite finished so my dad said he would get it finished during the break time while they went out for their lunch. They could move on to the next job then he said, as they were running late.

He finished off the job and was packing up and was about to leave when woman came in he looked up and said hello, it was a very old church(medieval) and so thought maybe she is taking a look around. She did not answer and carried on walking maybe she is looking for the door out he thought because it was not directly obvious. He told her the direction for the door but she carried on so he didn't bother telling her she was heading the wrong way and that way was now blocked, maybe she does not want the door and she's either ignorant or deaf. So he ignored her, he saw her from the corner of his eye walking towards a wall and wondered what she was looking at. She did not stop though and carried on walking, straight through the wall. He said the whole incident occurred in just a minute or two.

Obviously shocked and a bit shaken by it he spoke with the Priest who asked for a description. It was indeed the ghost of a woman that is sometimes seen he said. The wall she walked through had once been a doorway. It was later blocked.

The woman is looking for her husband and child to whom she was devoted to. During the time of the plaque, people were buried outside the city walls because of the risk of infection. So even in death she was separated and looking for them.

This is one of my experiences
Has anyone had something similar happen to them?

When I was about 8 I first saw what I can only describe as being like the solid shadow of a man standing in the corner of my bedroom. Who was my best friend refused to come into my room, and rarely visited, when she did she would stand at the door only and make her excuses to leave whenever I said for her to come in. I never told her about what I had seen because I thought she would think I was nuts, or pass it around school.

Later when I was 11, I was reading when I felt that someone was watching me and so I turned around and again saw the solid shadow of a man peering over and watching me, he saw that I was looking at me and so disappeared. I do not think it was the same person though because on this occasion I felt only curiosity and no kind of malice at all, which I had felt from the other.

It was not until a few years later when my friend and I were both talking about ghosts that she told me the reason she would never come to my house. It was because one time she came she thought she saw the ghost of a man standing by the window, and she felt that he did not like her being there and that was the reason she would never come to my house.

More recently since my father died my mother has moved into the smaller bedroom which had been mine. She said to me last year that she thought she saw someone standing in the corner of the bedroom, I did not tell her I knew already because I had been seeing someone standing there since we moved into the house when I was 8 years old. I don't think it would make her feel any better about being in the house alone now if she was to know there indeed was someone in the bedroom and it was not just a strange looking shadow

The house I live in now

The following, I assure you, is true.
Ghost number one.

He is not related to Mr and Mrs Davies and is a youngish man usually seen as a dim shadowy looking figure at the bottom of the stairs who is a bit vindictive. He stares at someone going up the stairs sometimes and can sometimes be seen from the corner of your eye or vaguely as a reflection. He was nasty towards my daughter Kathrynn a while ago when we had gone out shopping one night and so she was on her own. She said that not long after we had gone out the tv began to act strangely and also the lights. She thought she heard something and saw someone from the corner of her eye in the hallway. She dashed upstairs to her bedroom and heard a dragging sound from the hallway and it then sounded like he was coming up the stairs and she said he then began laughing at her. Kathrynn does not like being in the house at night now unless we are there. We have never been able to find out why there is a dragging sound in the hallway or who he is.

This is Mr Davies an old man who used to live here before us. We vaguely see him, again as a reflection or from the corner of your eye, he's seen walking from the kitchen past the living room door, he stops briefly at the door and looks in, then walks to the front door. Because of what he does we think he is carrying out his nightly routine of clearing up in the kitchen, washing the milk bottle and going to put it out for the milkman, stopping first to check the room, and locking up. We have heard a breathing sound from the living room in front of the TV its the sound of someone asleep. We found out later from the last person to have seen Mr Davies, that she had seen him from her house in the kitchen rinsing out the milk bottle and that he gave her a little wave and she did not see him again. When she had not seen him for a couple of days she was worried. There was no answer when knocking on the door so she got in touch with Warden Call who visit old people every month to see if they are OK. They carry a spare key to let themselves in case there is any problems. He had died in his sleep in front of the TV.

Mr Davis was devoted to his wife. She has been seen in the room that Kathrynn has, she is rarely seen now but she has been seen standing looking out of the window. Also on a couple of occasions my partner Michael has heard her. Once when my son Simon had been putting treacle on a scone he got some on the floor and did not clean it up, Michael walked in and stood on it so he went upstairs to wash it off, saying 'treacle, I hate treacle, you've got it all over!' As he was washing it off a female voice said behind him 'You don't like treacle then.' Kathrynn was out, Simon was cleaning up his mess and I was in the room, no-one else could have said it. Another time was when again Michael was in the kitchen and a voice said 'hello.' He asked me if I had said something, which I had not, and as I pointed out to him why would I say hello.
I would be interested to hear of others true experiences.
