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 would interfere with memory and learning.
Why can we have nightmares?
Dreams that assist you deal productively with emotions, memories, and other information could seem very helpful.

What influences dreams?
Some factors that affect us when we’re awake also can influence our dreams.
Health conditions – One of the most important influences on dreams is what proportion or how little you’re sleeping. Being sleep-deprived for an evening or two (or more) can make parts of your brain far more active once you finally do slip into paradoxical sleep. You’re likely to possess more vivid dreams if you’ve had some restless nights. You’re also more likely to recall those dreams, too.
Being pregnant is additionally a catalyst for vivid dreaming. Increased hormone production affects the way your brain processes thoughts and emotions. This often results in some intense dreams.

Anything that affects your waking mood is probably going 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 awaken throughout the night may end in you awakening more frequently within the REM stage. When that happens, you’ll probably remember more of your dreams.
Daily activities – Just as little or interrupted sleep often leads to more vivid dreaming, an honest night’s sleep will hamper the extreme dreams you’ll recall.
A small study trusted Source found that one great way to sleep more soundly is to exercise within the morning. an honest run or other cardio workouts before noon helps set your clock in order that you’re more inclined to nod off faster and spend longer in deep sleep than if you didn’t exercise or if you exercised late in the dark.
Runners and other serious fitness enthusiasts tend to spend less time in dreamy paradoxical sleep, which is one among the lightest stages of sleep. Also, the more effectively you’ll de-stress during the day, the less likely you’ll be to bring stress and anxiety to bed. Which ought to help hamper nightmares and interrupted sleep each night.
How to remember your dreams – One of the explanations dreams are often difficult to recollect is that the brain chemical related to memory — norepinephrine — and therefore the brain’s electrical activity that helps with recall are at their lowest levels when you’re dreaming. In fact, if you’ve got a dream but don’t awaken during the dream, you won’t be ready to commit it to memory. The dreams you remember are those that are ongoing once you awaken.
Two ways to assist recall your dreams is to inform yourself as you’re falling asleep that you simply want to recollect your dream. If that’s your last thought, you’ll be more likely to awaken with a dream still somewhat fresh in your memory.
Since dream recall is often easily interrupted by even the slightest distraction, you ought to attempt to remember the maximum amount of your dream as soon as you awaken. Don’t get out of bed or believe anything. attempt to grasp whatever images or memories you’ve got of your dream and write them down on a pad next to your bed or on your smartphone.
