This is what some people have nightmares about.
A group of eight kids were left immobile on 'The Joker' roller coaster in Six Flags Over Texas after it malfunctioned and broke down.
The roller coaster stalled as storms began to roll through the Arlington area, which caused the students to be stuck on their backs.
The rescue finally ended at around 3am on Saturday, and the fire department reports that no one was injured.
