The house I grew up in was build by my dad in 1989. Its located I a quiet family house area in a small old town in the north of Germany.
Strange things started already to happen under the building process. My dad would be at the building area every day, while my mum was back home with me and my siblings.
One evening, my dad was cleaning the area for the night, a dark big furry dog came up to my dad and looked at him like he wanted to play. My dad thought the dog might belong to one of the neighbours and started playing with him before going back home.
From that day the dog came back every evening to the building area and one evening my mum was there as well - but she couldn't see the dog sitting right in front of my dad. My dad thought first my mum was joking, but the dog really was invisible to her!
After the house was finished the dog didn't return, but other strange things started to happen. Books would fall out the shelves, we heard footsteps, a jam jar on the table moved a bit in front of our eyes (nobody touched it or sat close to it) and random things would disappear and turn up again at the strangest places.
My room was on the top floor, right next to my brothers room.
Something about his room always creeped me out. The room felt much colder than every other room in the house and I always had the feeling that someone watched me from his room or in his room.
My brother uses to lift his shoulders and says: "I don't know,...maybe..." when I ask him if he ever experienced anything strange in his room.
One evening, and that was maybe the scariest event that happened to me in our house, I was doing my school homework. It started getting late and as I was sitting there trying to concentrate I could hear my brother playing the guitar through the wall.
The guitar music got louder and more aggressively and I knocked against the wall to signal to him that I was disturbed by his play. It stopped - and even answered with knocking back.
I continued my homework and suddenly the guitar playing started again, louder than before. I knocked against the wall and it stopped - and knocked back.
I was really pissed off by then but continued doing my homework, and of course, the guitar playing started again.
I got up and went to his door, ready to burst into his room, but found his door locked.
I had enough and, yeah I was a child then, went downstairs to tell my mum.
My mum looked very surprised when I told her about my brother playing guitar, answering my knocking and locking his door. She told me that she was pretty sure he wasn't home. He was supposed to stay at his girlfriends home that night.
I told her that I'm a 100% sure he IS home and that he locked himself into his room.
My mum and I went upstairs and we entered his UNlocked room. It was cold, my brother wasn't there and his guitar was standing in the corner where it belonged.
Well, if my brother would have been there we would definitely heard him leave while I was downstairs talking to my mum. He's been at his girlfriends place the whole evening.
My parents still live in the house and they still experience things there. So do I and my siblings when we visit. But whatever is in our house or on the ground it's build on, seems playful and my parents told me they feel like the ghost just says: "Don't forget about me, I'm still here". It seems like I'm the only one who is scared of it. And the ghost probably knows that...
