From Fantastic to Mundane

My mind wanders; sometimes it hits upon fantastic ideas that would be great for an SF story or RPG. Then my brain starts imagining the outcome of those fantastic ideas. Then those outcomes spawn more mundane concerns. Here's an example:

• What if all of our stuff just vanished, leaving us behind. Alien Space Bats fuck with us in a way similar to the Emberverse.
  
• Ugh. A lot of people in airplanes and high buildings are going to fall to their death.
  
• I wonder what the odds of that happening to me are?
  
• my office is on the ground floor - if I fall, it will be into the pit where my building's basement is.
  
• Wait... Does my building even have a basement? I imagine it does, but I've seen no evidence of that. There's no parking garage, no low windows, and no doors that lead down.

From post-apocalyptic scenario to wondering if my office has a basement... in seconds!
