But first up, rapid fire syndrome facts.

Alien hand syndrome is a rare disorder where a limb acts on its own.

A hand might grab objects, untie a shoe, or grab someone's clothes and refuse to let go.

And as you can imagine, this can often get a person into socially inappropriate situations.

It's also called the Dr. Strangelove syndrome, since the title character in the Stanley Kubrick movie infamously loses control of his right arm.

Foreign accent syndrome is exactly what it sounds like.

The person suddenly speaks in an accent they're completely unfamiliar with, and most cases are from a stroke, head trauma, or a brain tumor.

In World War II, a Norwegian woman, Astrid, was injured by bomb shrapnel, and ever since, she spoke with a German accent.

And since many Norwegians resented Germans, especially during the war, she was socially ostracized, and locals thought she was possibly a German spy.

The Jerusalem syndrome is a religious delusion where people begin to believe there are biblical figures after visiting the holy city.

Many have walked around dressed in robes, claiming to be the Messiah or Angel Jesus.

There's also the Paris syndrome, especially with Japanese tourists, where they become acutely distressed and sad because the city just didn't live up to the hype.

One man was so disoriented that he thought he had become the French monarch, King Louis XIV.

The Fregoli syndrome is a rare syndrome where a person believes that different people they are coming across are actually a single person constantly changing their disguise.

It was named after the famous French actor who was known for his quick change stage impersonations, Leopoldo Fregoli.

A middle-aged female patient was recovering from catatonia when she thought that her physician was actually her first husband's first wife's daughter in disguise, and she had been keeping her in medical detention with police involvement.
