dream about scarry home

I was in my home which looked out to some kind of fair or pier or something. There was a roller coaster in the distance that had broken down and was on fire and all of the people were piling out of the rollercoaster to the sides of the coaster where the emergency stairs were located. They were filing down the coaster when the fire started to make the rollercoaster crumble and people just began to plumet to their death, and I was sitting in my house thinking, somebody has got to call the ambulance. so i started to look for a phone, and then I woke up.
