One night, London police were called about a possible suicide attempt on the counterweight of a crane at a construction project, where a young girl was perched precariously 130 feet in the air. So while helpful passersby probably shouted words of encouragement or took bets on how big the splat would be, a fireman climbed the crane to try to talk her down, only to find her sleeping.
That's right, the 15-year-old girl was sleepwalking so hard she climbed a fucking crane. Anyone who's ever had a flying dream knows that your unconscious mind sometimes gets sick of being trapped on this shithole your waking mind calls the ground. Her mind just decided to do something about it. Unfortunately, when the firefighter found her, she'd sleepwalked out onto a narrow beam and was in danger of having history's most realistic "falling dream" followed immediately by the much less common "having your body collected with a huge cartoon spatula dream."
Not wanting to alarm her and make her fall, the fireman did what any responsible public servant would and went through her personal belongings. He found her cell phone and gave her folks a call. Together, they hatched a plan to get the girl to safety. The fire fighter hung up and the parents called back, waking her up.
The only recorded instance of positive parental nagging.
