Sounds like a horror movie! My worst story is probably running one last time through an abandoned beautiful hotel to show a friend before they tore it down. Wide opening to get in (in an alley, but other 3 sides were busy downtown area. Only in there for 15 minutes or so, and the exit/opening was covered in plywood. So, mind was racing "is there a cop right there waiting for us", "will we be mugged". For some reason, while walking through, I noticed a door that seemed to possibly be open - it was (held by a tiny rock), and we snuck out the door - which had a big risk of police presence on a busy main street, but it was in the wide open and opposite side of the hotel
