Dementors?

Tonight as we said goodbye to our daytime guest, we noticed the sky. Or rather it seemed, the sky noticed us. The black clouds were rolling above us with incredible speed. It seemed like a dark force was above us!

"Dementors are among the foulest creatures that walk this earth. They infest the darkest, filthiest places, they glory in decay and despair, they drain peace, hope, and happiness out of the air around them... Get too near a Dementor and every good feeling, every happy memory will be sucked out of you. If it can, the Dementor will feed on you long enough to reduce you to something like itself...soulless and evil. You will be left with nothing but the worst experiences of your life."
—Remus Lupin to Harry Potter

Storm or Dementors? I'll take the storm everytime!
