It means that a lot of people had weird dreams that evening.
There must have been an air traffic controller dreaming about a non-squawking airplane infringing his airspace, a few commercial pilots dreaming about having to go-around because of you, and a bunch of shoppers dreaming about someone descending in the midst of them by parachute.
But the weirdest dream would have been from the concierge of that building... Being harassed by a total stranger needing to get onto the roof "because his plane is up there" and then not just finding a PA-28 but also a ski ramp on top of his building. And then the pilot just gets in and takes off!
The only thing left to wonder... What did DFC dream of that night?
