I'm really interested to know when we are sleeping how a series of stories come to our mind that we called this process dreaming. If you know a useful article on this topic, please tell me thanks.

  • $\begingroup$ Relevant xkcd. Researching & understanding sleep is hard, even without going into dreams. I'm not an expert, but my best guess is that a lot of this is just not currently known. $\endgroup$

  • $\begingroup$ Hi @Zahra - normally we strongly encourage edits to improve questions, and I like many that you've made, however they change your question a little too much for one that already has an answer. I'd strongly encourage you to both A) Edit this question along the lines of AliceD's suggestions, without disrupting the central point of the original question, and B) Ask a new question along the lines of your edits - I think that second question will be a good one. Thanks! $\endgroup$

1 Answer 1


Dreams are hallucinations that occur during certain stages of sleep. They’re strongest during REM sleep, or the rapid eye movement stage, when you may be less likely to recall your dream. Research is yet to reveal the true reason of dreams. But we know for sure it is not one reason.

Speculated Reasons:

1. Dreams as fight-or-flight training

One of the areas of the brain that’s most active during dreaming is the amygdala. The amygdala is the part of the brain associated with the survival instinct and the fight-or-flight response.

One theory suggests that because the amygdala is more active during sleep than in your waking life, it may be the brain’s way of getting you ready to deal with a threat.

2. Dreams as memory aides

One widely held theory about the purpose of dreams is that they help you store important memories and things you’ve learned, get rid of unimportant memories, and sort through complicated thoughts and feelings.

Research shows that sleep helps store memories. If you learn new information and sleep on it, you’ll be able to recall it better than if asked to remember that information without the benefit of sleep.

How dreams affect memory storage and recall isn’t clearly understood yet.

3. Creative times!

One theory for why we dream is that it helps facilitate our creative tendencies. Artists of all kinds credit dreams with inspiring some of their most creative work. You may have awakened at times in your life with a great idea for a movie or a song, too. Without the logical part of the brain working, emotional and illogical thoughts take over your mind!

Eectroencephalography (EEG), electro-oculography (EOG), and electromyography (EMG) are used to monitor neurological data from the brain to reveal information about neurological activities in the sleeping brain.

Here is a scientific literature (pdf) you can go through for in-depth study ( this link leads to ResearchGate page, you can read it there or download the pdf) : https://www.researchgate.net/publication/281071308_The_Role_of_Dreams_in_the_Evolution_of_the_Human_Mind
