Here’s a look at the most bizarre sleeping habits of 14 highly successful people.

Cruise's snores are apparently so bad, he sleeps in a sound-proof 'snoratorium.' Once a nursery, Cruise converted the small room at the back of his house to a sound-proof space where he can snore in peace.

'Whoever uses the snoring room cannot be heard outside the locked door,' an alleged visitor to the actor's house told the Daily Mail. 'It's very small, comfortable, and dark.'

Every day at 5 p.m., the prime minister would drink a weak whiskey and soda before taking a two-hour nap. Churchill said this short 'siesta' allowed him to get one and a half day's worth of work out done every 24 hours.

Churchill would often work through the night and became known as quite the
night owl. Due to his irregular sleep schedule, he was said to hold War Cabinet meetings in his bath.

'I've got to sleep 15 hours to sing the way I want to,' Carey told Interview magazine in 2007.

The singer also admitted to sleeping with 20 humidifiers around her bed, which soothe sore throats and add moisture to dry air. 'Basically, it's like sleeping in a steam room,' she said.

According to Lisa Rogak's book 'Haunted Heart: The Life and Times of Stephen King,' the science fiction writer has an odd nighttime ritual.

'I brush my teeth, I wash my hands. Why would anybody wash their hands before they go to bed? I don't know,' he says. 'And the pillows are supposed to be pointed a certain way. The open side of the pillowcase is supposed to be pointed in toward the other side of the bed. I don't know why.'

Charles Dickens slept facing north to improve his creativity.

Eminem puts tin foil on his windows to keep out the light.

Most people put dark shades on their windows to keep their rooms dark, but rapper Eminem takes it to another level by wrapping tin foil around his windows to get better quality sleep.

He also listens to white noise throughout the night, which he claims helps him sleep better when travelling between different time zones.

Arianna Huffington turned her bedroom into a 'slumber palace.'

After collapsing from exhaustion in 2007 -- and waking up in a pool of her own blood -- Arianna Huffington became an advocate for getting a good night's sleep.

Huffington turned her bedroom into a 'slumber palace,' complete with a canopied bed and blackout curtains. Before bed, she turns off her phone and plugs all her electronics in to charge overnight -- outside of the bedroom. She then takes a hot bath, filled with Epsom salt and lavender oil, to calm her mind and help her forget the stresses of the day.

What she wears matters as well, and Huffington only sleeps in garments meant for slumber; no old gym t-shirts allowed here. Finally, she dives into a book on poetry or philosophy and lets it lull her to sleep.

Leonardo da Vinci's sleep schedule included 20-minute naps every four hours.

Da Vinci followed an extreme form of a polyphasic sleep schedule called the Uberman sleep cycle, which consists of 20-minute naps every four hours.

This unconventional sleep cycle may have given the artist/inventor/scientist more awake time during his days, but could have also made it difficult for him to work on long-term projects.

Inventor Nikola Tesla never slept for more than two hours a day.

Tesla got more out of the day with his limited sleep schedule. Like Da Vinci, Telsa also followed the Uberman sleep cycle and claimed to never sleep for more than two hours a day. He once reportedly worked for 84 hours straight in a lab without any rest.

'I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success ... Such emotions make a man forget food, sleep, friends, love, everything,' he said.
