Back in November/December 1998 we briefly lived in a rather odd back to back house. It backed some shops and had been divided in to two. The place was freezing cold until the heating got working. Almost immediately out of the ordinary things started to happen.
I was in bed one morning and just before getting up. A male voice said very clearly in my ear 'That's all I need!'.
Then the electricty turned itself off at the main switch frequently. A black shadow walked across the bedroom blocking the light from under the door as it passed and obscuring the curtains.
One night I sat up on my own watching a late film which finished around 3am. I decided to set the phone alarm as I still had to be awake by 7.30am. As I was setting the alarm I turned my head to see a black tornado by the door to the stairs. It hovered there for some reasonable seconds before I looked away. When I looked back it had gone.
I went up to bed and had been there for about 10 minutes when the bedroom phone rang. There was no one there.
The television and video frequently turned themselves off as did the washer. It was more a nuisance more than frightening. But when I moved the black tornado appeared again one night in the new house just before I went to bed...
