Well....since you asked! ...No I have not seen one.... But I have noticed some odd things going around ny house. One time I walked passed the hallway closet... Which was PACKED, due to a laundry basket that pushed against the door. The door was either fully closed, or slightly ajar because there could be no median. If the door lock gear was not properly latched by having the door closed all the way, the door would instantly be pushed open from pressure from the laundry bin. Well, I was standing by the closet and the door pops open without touching it.
Another time, within a close amounts of time as the previous experience. I was in the bathroom, conveniently located across from that closet... And I had put my comb into my brush. Ya know... Took the comb and put it in between the little posts in the brush.... Well... Next thing I know the comb sorta pops out the brush (i didn't see it pop out...) But I caught it falling down into the sink...
This seems like a fun topic... Anyone else have an unexplained story?
