Explanation:
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. Much is known about the role of sleep in regulating our metabolism, blood pressure, brain function, and other aspects of health. But it’s been harder for researchers to explain the role of dreams.
When you’re awake, your thoughts have a certain logic to them. When you sleep, your brain is still active, but your thoughts or dreams often make little or no sense. This may be because the emotional centers of the brain trigger dreams, rather than the logical regions.
Though there’s no definitive proof, dreams are usually autobiographical thoughts based on your recent activities, conversations, or other issues in your life. However, there are some popular theories on the role of dreams.
The role of dreams
Researchers still don’t entirely agree on the purpose of dreams. There are, however, some widely held beliefs and theories.
Dreams as therapists
Your dreams may be ways of confronting emotional dramas in your life. And because your brain is operating at a much more emotional level than when you’re awake, your brain may make connections regarding your feelings that your conscious self wouldn’t make.
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.
Fortunately, the brainstem sends out nerve signals during REM sleep that relax your muscles. That way you don’t try to run or punch in your sleep.
Dreams as your muse
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 logic filter you might normally use in your waking life that can restrict your creative flow, your thoughts and ideas have no restrictions when you’re sleeping.
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 showsTrusted Source 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. But dreams may help the brain more efficiently store important information while blocking out stimuli that could interfere with memory and learning.
Why do we have nightmares?
Dreams that help you deal productively with emotions, memories, and other information may seem very helpful. The occasional nightmare is considered a dream that’s simply more frightening or upsetting. Nightmares tend to be caused by stress, anxiety, or sometimes as a reaction to certain medications.
However, if you have nightmares frequently, you could have a sleeping disorder. Regularly occurring scary dreams can be labeled a sleeping disorder if the nightmares:
cause you to be anxious about going to sleep
lead to frequent disruptions of your sleep
bring about other sleeping or psychological problems
Many people experience occasional nightmares throughout their lives. However, the American Sleep Association estimates only about 5 percent of the population experiences persistent nightmares as a sleeping disorder.
Foods
There isn’t indisputable evidence that certain foods lead to wilder or better dreams. But it’s clear that some foods may set the stage for you to remember your dreams better.
High-carb foods, for example, can give you quick energy. But after a while, they can leave you feeling down. Anything that affects your waking mood is likely to affect your unconscious mood, too. So, if a sugar crash has you moping around during the day, those feelings could carry over into your sleep.
Also, food that causes you to wake up throughout the night may result in you waking up more frequently in the REM stage. When that happens, you’ll probably remember more of your dreams.

Theories about why we dream include those that suggest dreaming is a means by which the brain processes emotions, stimuli, memories, and information that's been absorbed throughout the waking day. According to research, a significant percentage of the people who appear in dreams are known to the dreamer.
