This morning I was dreaming that I was some sort of clever architect or something, and I had designed this building that actually DOES have a 13th floor but it's so small that nothing fits in it. Somehow, I found myself inside the walls of this building, walking alongside two I-beams on top of each other separated by only a quarter inch or so, and that quarter inch was the 13th floor of the building. It seemed like I was in defiance of the traditional method of simply skipping the floor number of 13. My building actually had a 13th floor that could be labeled as such, and I seemed to be laughing at the lyrics.
But then it turned into a nightmare, and I found myself holding a wire from hand to hand. Now it seemed I had built the building this way so I could sneak around in the walls and into someone's bedroom (apparently it's a hotel) where I then proceeded to strangle them with the wire in my hands. But just as I started to do so, suddenly I felt like I was the one being strangled, and that's when I woke up startled.
Weird. I almost never have nightmares.
