My parents never really discussed the subject of "ghosts" with me as a child/teenager. Their reaction was always one of disbelief, but they never came out and said there is no such thing.
This attitude changed when we moved to a house on South 13 Street.
It was a very old building, recently sold to a neighbor. My parents did not know at the time of renting the flat, that the old owner who passed away did not have a very good relationship with the new owner.
It had been said that the old owner put a "curse" on the building saying that if the warring neighbor would purchase it, they would never had good luck with the structure. We were the fourth tenant in the upper flat in 3 years.
I was 12 at the time we moved and loved having my own room, until living in this flat. I always had the feeling that I was being watched. I woke often in the middle of the night to the sounds of people walking around and nobody was awake. The night time creeps were not just my problem, but the same with my younger brother and sister. It got so bad that none of us could sleep alone anymore.
My sister would talk of hearing people walking and noises at night. My brother was extremely young, but the back of the house became a place that seemed to terrorize him. Being the oldest, and having to set a good example, I finally started agreeing with my younger siblings and refused to stay in my back bedroom.
After 4 months of living in the upper flat, I overheard my parents talking saying that they had to move. My father was tired of running up to the attic to see who was walking around and my mother was afraid to be in the place alone during the day for the very same reason.
We moved quickly, and to everyone's relief, the night terrors that plagued us all ended with the move. From then on, when discussing the possibility of "ghosts" neither of my parents ridiculed the believers since they were also now believers.
