Last Sunday, early in the morning, maybe around 3 or 4am, my wife woke up and was fairly disturbed. It was raining fairly hard that night, but she could hear the sound of chanting coming from the mini park just in front of our apartment building.
Why would anyone be out in a little park, in the rain, at that time of night? My first thought was that they must have been drunk, figured the "stars were right" and were trying to summon Cthulhu or Hastur or Nyarlathotep. Them being drunk and unable to see the stars may have saved us all.
My wife, not having read Lovecraft, had the impression that they were summoning a demon or devil, like Satanists in some old 80's movie. Too bad she didn't wake me up to hear it. Instead she just closed the windows and went back to bed.
Either way, weird and potentially worthy of use as a hook in an RPG game some day.
