Amina and JessicaBody Fact AssignmentBody Fact: 90% of our dream’s content is forgotten when we wake up. Dreams are images, thoughts, sounds, voices, and subjective sensations experienced when we sleep. Even though you may not remember, you have three to six dreams a night. It’s quite common to experience difficulty recalling a dream. According to experts, within five minutes of a dream ending, we forget 50% of its content. 90% of our dream detail is lost 10 minutes later.When we go to sleep at night, we go through five different stages of sleep. The final phase of the cycle called the Rapid Eye Movement or REM stage, is where most vivid dreams occur. During this phase, the brain is almost as active as it is when you are awake. Our eyes move in reaction to what it is that we are dreaming about. All of our other muscles (other than those controlling eye movement and essential functions) remain paralyzed until we leave REM sleep. This paralysis prevents us from acting out our dreams,So, why do we forget about 90% of our dreams soon after waking up? Well, many researchers believe that the sleep cycle plays an important role in dream memory. We only remember the last of our dreams. It can be difficult to recall a dream if you wake up during one of the other phases of sleep besides REM. This however still isn’t a definitive answer, but many theories have been proposed as to why we forget what it is we dream about.One theory is that we learn and remember both by association and repetition. Dreams are usually unique and we often experience them only once. Since we can’t go back and re-experience our dreams, the details just escape from us. Another theory is that dreams are an unlearning process of junk memories. This information doesn’t grab our attention and therefore we tend to filter it out as unimportant. A study published explained that perhaps dream forgetfulness has to do with an important neurotransmitter called norepinephrine in the cerebral cortex. During dreaming, norepinephrine and electrical activity exist at very low levels in areas key to long-term memory, such as the prefrontal cortex. As the brain awakens, it starts to turn on processes needed for long-term storage. That is why you are more likely to remember a dream if you wake straight out of one. However, a lack of norepinephrine doesn’t completely explain why dreams are forgotten so easily. Well, researchers don’t know for sure why dreams are easily forgotten. Some think that maybe we are designed to forget our dreams. If we remembered all our dreams, we might not be able to distinguish them from real memories. Others say that our minds don’t actually forget dreams, we just don’t know how to access them. Dreams may be stored in our memory, waiting to be recalled. There are several scientific theories and studies out there, but there’s plenty more research that has to be done. Why we forget the content of our dreams is still not exactly known.ReferencesDreamsCloud. “Why Do We Have Trouble Remembering Our Dreams?” The Huffington Post, TheHuffingtonPost.com, 27 Aug. 2015, www.huffingtonpost.com/dreamscloud/remembering-dreams_b_8009552.html.Obringer, Lee Ann. “How Dreams Work.” HowStuffWorks Science, HowStuffWorks, 27 Jan. 2005, science.howstuffworks.com/life/inside-the-mind/human-brain/dream4.htm.Huguet, Julian. “Why Do We Forget Our Dreams?” Seeker, Seeker, 25 Mar. 2015, www.seeker.com/why-do-we-forget-our-dreams-1792564911.html.Hartmann, Ernest. “Why Do Memories of Vivid Dreams Disappear Soon After Waking Up?” Scientific American, 1 May 2011, www.scientificamerican.com/article/why-do-memories-of-vivid-dreams/.”What Processes in the Brain Allow You to Remember Dreams?” Scientific American, www.scientificamerican.com/article/what-processes-in-the-brain-allow-you-to-remember-dreams/.
