I believe that I have one. Once, whilst pet sitting in a new home, the couple showed me upstairs to my ensuite guest room and left me to get unpacked. It was February, dark and snowy outside. I saw double doors apparently leading to a balcony. I pulled them both open to get a breath of fresh air, and to my utter shock and surprise, there was a sheer drop down onto a concrete patio. They were in the process of adding a balcony but it hadn't happened yet. I was shaking as I closed the doors. I mentioned it to the owners, and they just replied that they didn't think I would open the doors. I still get chills when I think of looking at that drop and how close I came to putting my foot out.
There have been two other specific incidents, one of which is completely unexplainable. So for me, it's a yes.
