I have always enjoyed reading or hearing about ghost stories growing up but would take them with a pinch of salt, who really knows what's 'out there'! However for the first time in my life I had an experience that I could not explain and to this day I always check the attic door.
I live in a new (ish) house that was built upon an old cottage years back. There is a large 5ft by 3ft door to the attic which to reach you have to stand on a chair or use the ladder. I never open it as it is very heavy and sits down into a 6inch deep groove. My partner always deals with it. During some bad weather we opened it to prevent pipes freezing and he forgot to close it before going to work the next day. I noticed this and got a chair and went to close it. Fine no problem all done. It was heavy but I turned it and it sat into its housing. It was quite a windy day outside and miserable. My partner rang to remind me to close it as he had forgotten. I told him I had, then my young child went up to the bathroom and shouted down that I hadn't closed it as it was open. I shouted up 'no it's closed' and went to check.
So up I went and looked and there it was as before opened and tilted at an angle (its not a hinged door it is movable and we normally turn it at an angle so it can't fall through the opening (for safety). I went cold with shock and had to think back did I really get the chair and close it. I knew I had. Again I got the chair and slowly (being frightened to even look upwards as I did), went and closed it again.
To this day no one can explain it. I could blame the wind through the attic, but don't think it is possible. What else could it be? I have never had an incident before or since but I do look up over my shoulder slowly most days to check it's closed with a fear that I will see it open again as that would confirm for me something is up! To banish my fears I shrug it off... But will always wonder...
