It is difficult for me to try to explain this bizarre occurrence. I am very uncertain what to call what happened. I have never found any information regarding such an event and I am puzzled to this day about what took place. I am merely writing about this in search that someone may have an idea.
This event took place when I was around 6 or 7 years old. I am now 24 and I recall it quite well. I lived in a fourplex in New Westminister, BC Canada with my mother and brother. My brother shared a room with me. He is nearly 3 years older than me and he recalls this as well.
Our room had a large single pane window, with a large window sill. We used to set things on the window sill occasionally as people do to decorate the room. Many mornings after one of us had placed a couple of toys on the sill the day before, we would wake to realize that a toy had seemed to duplicate itself. A complete, identical copy of one of the toys would be beside the original one. It was always only one toy at a time that would duplicate, and it was always one that was not large, such as a McDonald's Happy Meal toy or a small doll. I will add that we didn't have multiple versions of a same or similar toy.
I am not sure if a window can be haunted or perhaps there was a spirit that was toying with us or if the window was some sort of paranormal portal or what. I have no idea and I still think about this. I recall this happening several times. As a child I was even more baffled about it and it seemed almost like we were playing a game with an invisible force and we found it rather amusing.
As an adult, it is just confusing to reflect on such a strange occurrence. Could this be some sort of haunting that I am unfamiliar with...? Can entities do such things to play with people? Has anyone heard of or had any experience like this?
