Most people dream about 1-2 hours a night and have an average of 4-7 dreams each night.
Five minutes after a dream, half of the dream is forgotten. Ten minutes after a dream, over 90% is forgotten. Write down your dreams immediately if you want to remember them.
Dreams are more than just visual images, and blind people do dream. Whether or not they dream in pictures depends on if they were born blind or lost their vision later.
Some people (about 12%) dream only in black and white while others dream in color.
If you are awakened during a dream, you are much more likely to remember the dream than if you slept until a full night's sleep.
While you sleep at night may be the best time for your brain to consolidate all your memories from the day.
As those who invest in dream dictionaries can attest, dreams almost never represent what they actually are. The unconscious mind strives to make connections with concepts you will understand, so dreams are largely symbolic representations.
Japanese researchers have successfully developed a technology that can put thoughts on a screen and may soon be able to screen people's dreams.
Caffeine works to block naturally occuring adenosine in the body, creating alertness. Scientists have discovered this connection and learned that doing the opposite - boosting adenosine - can actually promote more natural sleep patterns and help eliminate insomnia.
A study published in the journal Sleep Medicine described how Disney creators used real sleep disorders in many of their animated pets.

10 fun facts about brain
Your brain stopped growing at the age of 18.
You can't tickle yourself because your brain distinguished between unexpected external touch and your own touch.
While you sleep, your body produces a hormone that may prevent you from acting out your dreams, leaving you virtually paralyzed.
Every time you blink, your brain kicks in and keeps things illuminated so the whole world doesn't go dark each time you blink (about 20,000 times a day).
If you are snoring, you are not dreaming.
Laughing at a joke is no simple task as it requires activity in five different areas of the brain.
Just because you don't remember your dreams doesn't mean you don't dream. Everyone dreams!
Those who are left-handed or ambidextrous have a corpus collosum (the part of the brain that bridges the two halves) that is about 11% larger than those who are right-handed.
Brain waves are more active while dreaming than when you are awake.
Scientists discovered that men and women's brains react differently to pain, which explains why they may perceive or discuss pain differently.

Another 10 interesting facts about our brain
The weight of the human brain is about 1.3-1.4 kg.
Your brain uses 20% of the total oxygen in your body.
The next time you get a fever, keep in mind that thehighest human body temperature ever recorded was 46.5 C –and the man survived.
It is thought that a yawn works to send more oxygen to the brain, therefore working to cool it down and wake it up.
Your brain is 60% white matter and 40% gray matter.
Every time you recall a memory or have a new thought, you are creating a new connection in your brain.
Memories triggered by scent have a stronger emotional connection, therefore appear more intense than other memory triggers.
Memory is formed by associations, so if you want help remembering things, create associations for yourself.
A newborn baby’s brain grows about three times its size in the first year.
Excessive stress has shown to alter brain cells, brain structure and brain function.

10 interesting facts about our brain
Our brain is made up of about 75% water.
While awake, our brain generates between 10 and 23 watts of power, enough energy to power a small light bulb.
There are no pain receptors in the brain, so the brain can feel no pain.
There are over 150,000 km of blood vessels in the brain.
If our brain loses blood for 8 to 10 seconds, we will lose consciousness.
Boredom is brought on by a lack of change of stimulation, is largely a function of perception, and is connected to the innate curiosity found in humans.
Our brain consists of about 100 billion neurons.
The human brain is the fattest organ in the body and may consists of at least 60% fat.
Women tend to take longer to make a decision, but are more likely to stick with the decision, compared to men, who are more likely to change their mind after making a decision.
Our skin weighs twice as much as our brain.
