Sleepwalking, also known as somnambulism, is when people get up and walk around while asleep. It's more common in children than adults.

Which of these is a short sleep period, typically taken during daytime?
- Tinner
- Nap
- Sobriquet
- Early bird
A nap is a short period of sleep, typically taken during daytime hours as an adjunct to the usual nocturnal sleep period. Naps are most often taken as a response to drowsiness during waking hours. A nap is a form of biphasic or polyphasic sleep, where the latter terms also include longer periods of sleep in addition to one period. For years, scientists have been investigating the benefits of napping, including the 30-minute nap as well as sleep durations of 1–2 hours. Performance across a wide range of cognitive processes has been tested.

- Snow White
- Cinderella
- Mary Mary
- Goldilocks
"Goldilocks and the Three Bears" (originally titled "The Story of the Three Bears") is a 19th-century British fairy tale of which three versions exist.The original version of the tale tells of an obscene old woman who enters the forest home of three bachelor bears while they are away. She eats some of their porridge, sits down on one of their chairs and breaks it, and sleeps in one of their beds. When the bears return and discover her, she wakes up, jumps out of the window, and is never seen again. The second version replaced the old woman with a little girl named Goldilocks, and the third and by far best-known version replaced the original bear trio with Papa Bear, Mama Bear, and Baby Bear. "Goldilocks and the Three Bears" is one of the most popular fairy tales in the English language.

Which of these is also known as one's internal alarm clock?
- Circadian clock
- Human watch
- Atomic clock
- Gregorian clock
A circadian clock, or circadian oscillator, also known as one’s internal alarm clock is a biochemical oscillator that cycles with a stable phase and is synchronized with solar time. Such a clock's in vivo period is necessarily almost exactly 24 hours (the earth's current solar day). In most living organisms, internally synchronized circadian clocks make it possible for the organism to anticipate daily environmental changes corresponding with the day–night cycle and adjust its biology and behavior accordingly.

Which of these is known as the "sleep hormone"?
- Serotonin
- Cortisol
- Oxytocin
- Melatonin
Melatonin is a natural hormone that’s mainly produced by the pineal gland in your brain. It plays a role in managing your sleep-wake cycle and circadian rhythm. Scientists still have a lot to learn about all of its effects on the human body. Your pineal gland releases the highest levels of melatonin when there’s darkness and decreases melatonin production when you’re exposed to light. Because of this, melatonin has often been referred to as a “sleep hormone.” While melatonin isn’t essential for sleeping, you sleep better when you have the highest levels of melatonin in your body.

Which of these animals can sleep around 20 hours a day?
- Masai giraffe
- Dusky dolphin
- Meerkat
- Little Brown Bat
Little Brown Bats sleep for an average of 20 hours per day to conserve energy. The little brown bat actively hunts for a few hours after dusk, but then it typically retreats back to its roost to return to its slumber. The typical little brown bat needs to eat half their body weight each night to stay properly nourished, and mothers can end up eating more than their entire body weight during the period of a single night’s hunt. As a result, these bats don’t just sleep for most of the day. They also hibernate through the length of the winter.

How many hours a day does a dolphin sleep?
- Fourteen hours
- Nine hours
- Eight hours
- Ten hours
Dolphins need about eight hours of sleep a day, but their brains sleep in shifts. The right and left halves of their brains sleep four hours each, but at different times. Because dolphins need to tell themselves when to breathe, they can never fall asleep completely. Instead, dolphins only let one-half of the brain sleep at a time. Dolphins let the right side of their brain go to sleep while the left side stays awake to control their breathing. Then, a little while later, the right side wakes up, and the left side falls asleep.

Snails can sleep for up to how long?
- One month
- Five days
- Three years
- Ten years
If the weather is unaccommodating, snails can sleep for three years straight. Depending on the geography, snails can turn to hibernation in the winter or estivation, called “summer sleep,” to avoid dry climates. During dry seasons, snails secrete mucus all over their bodies for protection. However, this is not always the case. When the weather is ample, snails also tend to keep a regular sleeping pattern.

How many hours do wild elephants sleep at night on average?
- 2 hours
- Half an hour
- 13 hours
- 10 hours
Wild elephants average just 2 hours of sleep a night, making them the lightest-known snoozers of any mammal. Previous studies have looked at such habits in captive elephants, which sleep for 3 to 7 hours a day. But with more dangers and pressure to find food, wild animals tend to sleep less. So Paul Manger at the University of the Witwatersrand, Johannesburg in South Africa and his colleagues set out to monitor sleep in wild African elephants in Chobe National Park in northern Botswana. The team monitored two matriarchs for 35 continuous days. The elephants slept for an average of 2 hours a night, not in a single slumber but in four to five short bursts – a pattern known as polyphasic sleep. Most of their sleep occurred between 1.00 and 6.00 am, and the elephants snoozed in different places every night.
