When I was a teenager, my mates and I used to hang out a lot at the home of one of our friends. She had explained to us previously about several odd goings on that took place in her house, involving all her family. Although I never doubted anything that had happened there, I wasn't spooked as I hadn't experienced anything there myself. As my own house scared me half to death most of the time, anything 'differently' paranormal would have been a welcome change to me.
I'll start be filling in the story with the accounts of the family. In this house a presence was always felt by the family, doors would lock shut, doorknobs twisting and turning by themselves, the family dog acting really strange etc. The scariest experience (in my opinion) was a very tall figure witnessed upstairs in a doorway with a large head and two circling eyes (one pointing upward, one downward).
My own experience in the house happened one night when a gang of us were having a sleepover and we were of course telling ghost stories to freak each other out. I was sleeping by a fireplace and not exactly relishing the thought of a night by it.
It happened gradually at first, but slowly but surely, and with advancing speed, the interior shutters (the wooden kind you will find in Georgian houses) started flapping and shaking as if a sudden storm had taken hold. We rationalized this as an unexpected gale force wind. Now, this was during summer, and there was not a drop of rain or wind outside, let alone a storm. In any case, these were the inside shutters!
We were a bit scared, but then slightly relieved when we heard the front door slam and someone running up the stairs, followed by a flushing loo. We thought it was a family friend returning for the night, and I for one was glad of some human activity to break up this unexplained sort of activity.
Next day of course, we discovered no-one had come back during the night.
I can only guess it was poltergeist activity occurring in the house, but I thought that in those circumstances, entities or ghosts don't usually manifest.
Comments totally welcome, even if this was not the scariest story really.
