I have had a few strange things happen, not that I am saying I believe or don't believe in these things... But I do lean towards the don't.
Someone told me about a known old "haunted church" in our area once and mentioned when she last went she had bad luck and she would never go back, I wanted to see this for myself so she drove me down during the day and we had a look, I then asked to go there at night to see if the mind played any tricks. Walked around it and I had a peak through one of the windows and in the dark thought I could see a robed figure moving and fading away, walked around to one of the doors and put my ear to it and heard all sorts of knocking and banging and she heard it too and quickly decided we should go, I put all this down to my mind creating things. She was convinced that there was something going on as she said she had seen robes figures walking along the gravesite one night and disappearing into a stream. Anyway I thought nothing of this and said we should go back, she said no never again due to all this bs luck she was meant to of had. I said ok I will go on my own late one night just to prove that nothin would happen, I think it was around midnight started the bike up and rode up there by myself, went through all the country road up the hill where the church was, literally got to the top and all the electric and engine died... I quickly decided to head back, bit odd I know.
Another time when I was quite a bit younger my dad came into my room and rushed me out into the garage late at night and said quick come and listen to this, went to the garage with him, heard nothing, so said I was going he said no wait a bit, and then a loud heartbeating noise appeared from nowhere, I said that's you doing that and he said no it aint, and it continued to do it while he was talking, and it felt like there was something else there. Not much I know, but still odd.
Again when I was younger we were going to Ireland for a week, my dad had replaced some of the lightbulbs as they kept blowing for some reason. Went on holiday, house 100% Empty, when we got back every lightbulb in the hall was smashed on the floor, I thought ok maybe they some how fell, but these were the kind of lights that screw to the wall with an upright fitting... Can't really explain how they unscrewed themselves and ended up on the floor.
When I was still at secondary school I went to a friends house one night and we got onto this subject, I told him I didn't really believe in ghosts spirits etc and he said he did as his father had died when he was younger and he thought he was still with him, didnt want to say too much incase I upset him, but we wen upstairs to his older brothers room and started talking about it, he said yep all sorts of things have happened that I can't explain. He mentioned his dad and just as he said it something that was screwed to the wall fell off on the floor in front of me.
I know all these things will have some explanation, but it's all very Odd!
