I don't believe in ghosts....but I had a really really weird experience.
I was working in what is apparently one of the most haunted places in Great Britain.
I was running a wedding, when I heard children running around upstairs in the derelict area. Me being me, thought ah damn some of the kids/guests have gone through a staff door that leads upstairs to the derelict area. Kids will be kids they like to explore.
So up I went to the derelict area. As I was walking up the stairs I could hear what I believed to be at least 3 separate children running around. So I reach the derelict area and say loudly "anyone up here? You aren't in trouble but I need you to go downstairs as it's not safe up here"
I then see out of the corner of my eye a small child height shadow step out of a doorway and jump back in to one of the rooms.
It isn't dark in the derelict area in the day due to the amount of windows.
I walk down to the old TB ward where I saw the shadow and as I approach I hear stiffled children's giggles. I say again loudly "c'mon out, I don't want anyone hurt" as I turn in to the ward ....nobody there it's empty!!! No furniture nothing just an empty room.
I walked the rest of the derelict floor, but heard no more footsteps or laughter. If there were children up there they would have had to come past me to get out. As there's only one staircase accessible up there.
I returned downstairs convinced myself I just heard kids downstairs which sounded like they were upstairs, and I'm sticking to that!!!
