Dreaming

A dream is a succession of images, ideas, emotions and sensations that usually occur involuntarily in the mind during certain stages of sleep. The content and purpose of dreams are not fully understood,tough they have been a topic of scientific speculation, as well as a subject of philosophical and religious interest, throughout recirded history. The scientific study of dreams is called oneirology. 

In the end of the nineteenth century Sigmund Freud and Carl Jung put forth some of most widely known modern theories of dreaming. Freud's theory centred around the notion of repressed wishes. Carl Jung also believed that dreams have philosophical importance, but proposed different theories about their meaning. 

Since then technological advancements have allowed for the development of other theories. One prominent neurobiological theory of dreaming is the "activation-synthesis hypothesis", which states that dreams don't actually mean anything: they are merely electrical brain impulses that pull random thoughts and imagery from our memories. Humans, the theory goes, construct dream stories after they wake up, in a natural attempt to make sense of it all. 

Some believe that when we all sleeping, it's our body that rests where as our soul is somewhere else, semwhere we wish to be and what all we want to do ,we see in our dream. Some believe dreams are related to our past life. If you see some person in your dream whom you have never seen before or you see some place you have never been to before, they say it is related to your past life. 

Pain can also show you dreams. In one study, a lab induced " pins and needles" sensation manifested as a problematic shoe fitting in the subject's dream, while more intense pain can produce nightmares wherein the dreamer tries to escape the source of pain. 

Dreams also help you learn. The logic is this: anytime you make a memory, that new information has to transfer between several different parts of your brain in order to stick around for a while, and those same patterns correspond with the patterns of brain activity during sleep. Sure enough subjects who slept on their lessons showed greater improvement. 

The tone of a dream can set the tone of the following morning, for better or worse. Daytime mood and social interactions have been found to correlate with dream details. 

Some people have dreams and they remember just to vaguely to keep it in mind but then exactly what they saw in the dream happens for real and when they see it they feel like they have seen this before somewhere. It gives them a feeling of déjà vo. 

Everybody has their own way of thinking and everybody believes their own version of it. But it seems a good idea to think that those vague dreams are nothing as it is there are very less such dreams that we remember else we forget them once we are awake and even though we remember some bits and try to remember the rest the information seems to be going at the back of mind somewhere you can't reach.
