why do we see dreams while asleep?
2007-01-17 23:30:24 · update #1
While we are sleeping our brain uses this time to reorganize all the information it has taken in during the day. Current sleep theories suggest that dreams are just products of our brains trying to make sense of the information we took in during the day. It is also this school of thought that recommends getting a good nights rest before an exam rather than trying to stay up all night to study. A good nights sleep is necessary for your brain to solidify and organize exam material so it will be more accessible for you at test time.
There are 4 stages of sleep. The deepest stage of sleep is called REM (rapid eye movement). It is during REM when we experience dreams. Most dreams only last 5-20 minutes. In general, it takes individuals 4 hours to reach REM sleep. REM is also the most restful sleep and it is during this time that our bodies are repaired and rejuvenated. If you are sleep deprived. It is possible that you will fall into REM sleep much faster because your body needs REM sleep in order to function properly.
The Freudian theories on dreams speculate that are dreams are our unfulfilled wishes or desires.
The brain is a complex mechanism and it is difficult to say if we will ever know with 100% certainty why we dream.

Sleep is a more physiological phenomena than just thoughts and dreams.Our blood flow Is reduced when we are awake so that it is supplied to those organs which perform motor functions and need energy from blood.But when we sleep the heart creates a more uniform and constant blood flow movement throughout the body .When the blood flows more uniformly throughout the body and replenishes and nourishes all the organs and muscles and all other systems such as the nervous system etc and even the skeletal system with various minerals and calcium in the blood . So when ther is no body activity there is more nutrient absorption in the overall body because blood I'd not required to perform physical functions.That is why when body craves for sleep it means over billions of years it has developed a system where it starts craving the uniform blood flow it experiences during sleep and also to replenish and nourish itself with those nutrients present in the blood.

We all spend about one third of our life sleeping. It is quite interesting to find out that the amount of time we spend on sleep is roughly equal to that we spend in our work. When you are over 70 years old, you already spent about 20 years sleeping, in which 5 years you are dreaming! However, we still do not have a clear understanding of what is happening when we are asleep. Although technology is developing at a very fast rate, we still don't have a confirmed way of what we do in sleep and what purpose they serve.

Why do we feel thirsty and what actually is happening when we do faint by thirst?
Why do we feel bore at some times, and actually what the boring means?
Even, if one scientist says some reason for SLEEPING, the another scientist is going to deny it, in no time! Many times science contradicts with itself!!
So, better, let us say like this:
We are sleeping when we feel like sleeping, and also, where we couldn't resist that sleep! OK?
And after that sleep, our body and mind rejuvenated to a greater extent for sure!
IF YOU GET SOME CHEMICAL ANSWERS, FROM THE CHEMISTS FOR SLEEPING, AGAIN I WILL RAISE ONE MORE QUESTION OUT OF YOUR ANSWER..."WHY?".
Because, there are so many "whys", which can never be answered fully by our human mind!
FOR EXAMPLE; SLEEP IS A PARTIAL DEATH. AND WHAT THEN IS DEATH? WHAT WILL HAPPEN TO ONE WHO MET DEATH?
Yes,
Life is a mystery!
Enjoy it!
Dont ever confuse yourself!
Heat is Heater, and water is cooler!
Use it-and be a part of our Mother Nature-thats it!

Whenever I had no school I would feel sleepy by 4 or 5am, but since I have school now, I feel sleepy when it's 10:30pm or later.

Lots of reasons to feel sleepy.
Stressed
Bored
Too busy
Ate to much
When we are sleeping you are resting and energizing your body. Sometimes my dreams are so busy that all the sleeping I do doesnt help.

There are five levels of sleep:
1. you are nodding off. barely conscience.
2. you have nodded off. a semi dream state.
3. you are in a deep sleep
4. you enter REM (rapid eye motion).
5. your go into deepest sleep. Your brain produces adrenaline, serotonin, and other chemicals. you remain in level five sleep for about half an hour. the hormones your brain produces trigger your body to produce other hormones.
6. you return to level four sleep. here your body starts to repair itself. your require several hours of level four sleep to regenerate, or you will become rundown and sick. sleep is how your immune system repairs you.
