Dreaming

  You dream when you sleep, don't you ? everyone dreams something, every time they are sleeping, due to our brain still works, even if you are out of order, usually you can't remember what you dreamed, that means that you slept very well, but if you do remember something, it is usually the last moments before waking up, couple of seconds. It is believed that when you dream all movement and views are happening 7 times faster than in our real life, hey maybe real life is a dream too ? hum, but that is another topic.. it is faster, because the brain is so powerful and fast and can handle information so fast, that you can't believe it yourself.. to sum up, if you sleep 7 hours, you dream something for 7 hours and if the theory is right 7*7=49 hours (another longer life ?). But what can we dream ? the brain is so powerful, that it can remake everything it wrote, so if you saw something you will never forget it, just that it will be somewhere deep inside you. If you're dreaming a place you know and you walk to a place you still weren't, it will be created from different parts. The most enjoying dreams are when you understand and know that you're dreaming, that rarely happens, you can feel like a GOD there, just that this effect does not take long, in my opinion dreams can be created with machines, by creating some dream machine which could control it, it is even much better than some Virtual World, because your brain can send an exact signal of touch, taste to you, you can dream that you're kissing, if you ever kissed of course and think that the emotion is real, even if no one is near you, you can dream that you eat ice cream, even if you really don't, but the feeling is the same. I don't believe that dreams can tell the future, because the brain only executes things which already happened or from different parts put a puzzle together, not the future. Nightmares and etc. can be dreamed due to you have something inside you what scares you, usually if you're afraid or you watched a horror movie and went to sleep and your brain just creates something. Of course dreams can be very stressful, you might get insomnia or never get a good night sleep due to them, therefore you can lower the stress too, if you dream nice things. It is nothing more than your brain showing pictures to you with incredible speed in addition sometimes with taste and touch.

REM sleep stimulates the brain regions used in learning. This may be important for normal brain development during infancy, which would explain why infants spend much more time in REM sleep than adults (see Sleep: A Dynamic Activity). Like deep sleep, REM sleep is associated with increased production of proteins. One study found that REM sleep affects learning of certain mental skills. People taught a skill and then deprived of non-REM sleep could recall what they had learned after sleeping, while people deprived of REM sleep could not.

I was visited last night by a dream of so strange and vivid a kind that I feel impelled to communicate it to you, not only to relieve my own mind of the impression which the recollection of it causes me, but also to give you an opportunity of finding the meaning, which I am sill far too much shaken and terrified to seek for myself.

It seemed to me that you and I were two of a vast company of men and women, upon all of whom, with the exception of myself—for I was there voluntarily— sentence of death had been passed. I was sensible of the knowledge—how obtained I know not—that this terrible doom had been pronounced by the official agents of some new reign of terror. Certain I was that none of the party had really been guilty of any crime deserving of death; but that the penalty had been incurred through
their connection with some regime, political, social or religious, which was doomed to utter destruction. It became known among us that the sentence was about to be carried out on a colossal scale; but we remained in absolute ignorance as to the place and method of the intended execution. Thus far my dream gave me no intimation of the horrible scene which next burst on me,— a scene which strained to their utmost tension every sense of sight, hearing and touch, in a manner unprecedented in any dream I have previously had.
