Maybe!
I live in a house built in 1860.
A girl died here in the house I live in back in late victorian times.
One day 20 years a go I was talking to the neighbour over the front fence and a young girl, aged about 10 approached us, she walked up the garden path. She told us she used to live here. Her clothes were scruffy but were definately not of the modern era.
Me and my neighbour look at each other and raised our eyebrows in surprise, he said to me 'Who's she, do you know her?'
We looked round, she had only been standing 3 feet away from us, and she was gone. Disappeared, nowhere to be seen.
We both walked down the path to the road (about 20') to see where she'd gone and there was no sign of her.
We were both surprised to say the least, if my neighbour hadnt have been there I would doubt the story, but he was there as a witness and still to this day I believe we saw someone who had previously died.
