A minor weird phenomenon happened to me last week, when I was staying at my parents' home, in the Western suburbs of Paris. They live in a small house, built in 1998-1999, on the margins of a large wood. The house is fairly recent, and the place it has been built on doesn't have any historical significance. It is said that one of the favourites of king Louis XIVth once had a castle in the area, but I doubt this has any relevance with what happened. Anyway, the "castle" was dismantled in the late 19th century and replaced with rows of private residences. There is no history of haunting in the area and I spent years there without witnessing anything weird until last week.
So here comes the strange event :
One evening, we (me and my parents) had been watching TV on the ground floor. After the movie, we briefly chatted about their recently departed cat, a very nice animal, before I went to my room upstairs. Before going to bed, I decided to make a visit to the toilets, to empty my bladder. Now, there is a 4 m long corridor between my room and the toilets, which stand at the opposite. Once I came out of my room, the lights of the toilets were suddenly switched on. I immediately stopped in my way and thought : "oh, my mother must have been faster than me ! She must be in the WC". But at the same time I realized that the switch of the toilet's light was on the outside of the WC, clearly visible from the corridor and I hadn't seen any hand press it (I was looking straight at it when it happened). So I stood flabbergasted in the middle of the corridor, wondering what had just happened.
At that moment, I heard someone climbing the stairs. It was my mother coming up (my father was still on the ground floor). So I thought, if my mother and my father are not in the toilets, who is it who switched the lights on just in front of my eyes ??? I decidedly walked to the WC, opened the door, and it was indeed empty ! Bizarre !
Now I admit that downstairs, there is a light switch serving another room which sometimes does not work properly. One may press it without effect. So something similar may have happened upstairs. Maybe the switch had been pressed by someone into an unstable equilibrium. And when I walked into the corridor, the vibrations of my steps spread from the ground to the wall, and from the wall to the switch, imbalancing it and actually switching it on. That could be an explanation. But still, this isolated event was quite unsettling !
