Sleep is one of those funny things about being a human being -- you just have to do it. Have you ever wondered why? And what about the crazy dreams, like the one where a bad person is chasing you and you can't run or yell. Does that make any sense?

By studying brainwaves, it is known that reptiles do not dream. Birds dream a little. Mammals all dream during sleep.

Different animals sleep in different ways. Some animals, like humans, prefer to sleep in one long session. Other animals (dogs, for example) like to sleep in many short bursts. Some sleep at night, while others sleep during t­he day.

Dreams are the things that happen in a person's mind while they are sleeping. They are often similar to real life in some ways, but can also be very strange. Dreams can seem so real while they happen that the person might think that they are awake when actually they are asleep.
Sometimes a person realizes during a dream that they are dreaming, but keeps having the dream. This is called a lucid dream. This happens very little for most people, but for some people it happens often. During lucid dreaming the person will feel like they are controlling the dream, and will usually dream that they are doing fun things that they can't do in the real world.Max说他天天lucid dream.🙃
Most people remember their dreams in some way or another, even if it's only a small part, but children are very likely to remember most of their dream clearly. It's often easier for people to remember dreams if they write down what happened in the dream just after they wake up. Because of this, many people have dream diaries where they describe each dream they have.
Nightmares are dreams which scare or shock people. Nightmares are usually based around that person's everyday fears, like spiders or dark places, but even a dream that's not about those things can feel unpleasant. Nightmares are caused by many different things: being uncomfortable or in pain while sleeping, sickness, stress, or even eating right before sleeping.

What Is Sleepwalking?
Sleepwalking is very common in kids.
What Causes Sleepwalking?
Sleepwalking is far more common in kids than in adults. It may run in families, so if you or your partner are or were sleepwalkers, your child may be too.
What Happens During Sleepwalking?
Getting out of bed and walking around while still sleeping is the most obvious sleepwalking symptom. But young sleepwalkers may also:
sleeptalk
be hard to wake up
seem dazed
be clumsy
not respond when spoken to
sit up in bed and go through repeated motions, such as rubbing their eyes or fussing with their pajamas.

While most of us know how important sleep is to our health, many people may not realize that they're practicing poor sleep habits. Below is a list of seven bad sleeping habits to avoid as soon as possible.

AVOID eating too close to bedtime.

AVOID caffeine and nicotine close to bedtime.

AVOID alcohol before bedtime. 

AVOID technology in the bed. 

AVOID hitting the Snooze .

AVOID a warmer bedroom temperature.

AVOID odd sleeping hours. 

Different kinds of beds.

Cot

I have a cot in my office for my noon time snooze.

Flatform bed

Panel

A panel bed consists of a headboard and a footboard made of flat panels of woods.

Murphy
Ideal for rooms where space is at a premium, Murphy beds fold back into the wall when not in use. 

Poster
A poster bed is identified by its four vertical columns on each corner of the bed, sometimes supporting an upper panel that runs all the way around the bed and with curtains that can be pulled around the bed to enclose it.
Low Poster
A low poster bed still has four posts on each corner of the bed, but these are much shorter than the traditional poster bed and do not have an upper panel and canopy attached.
Half Poster
A half poster bed has four posts on each corner, with the two posts at the head of the bed considerably taller than the two posts at the foot. This makes them ideal for smaller spaces, providing much more space to move around the bed than a traditional poster.

Bunk

A bunk bed consists of two Twin-size beds stacked one on top of the other, with a ladder used to climb up to the top bunk. This type of bed is most commonly used by children, especially to save space when siblings share a room.

Futon
A futon is a Japanese-style mattress that is essentially a bed and a sofa in one. 

Hammock

A hammock is typically made of rope, netting, or a thin fabric that is suspended between two points. Although perhaps not ideal for sleeping in every night, hammocks are often used for relaxing outdoors in the summer or camping.

Sleigh
A sleigh bed has a curved foot and headboard, shaped to resemble a sled or sleigh. This type of bed came from the French and American empires of the early 19th century and is often made from heavy wood, steel, or iron, for a dramatic effect.

Crib
