Why Does 'How We Learn' Say Sleep Aids Memory?

After my best friend Lily Warren was assaulted, she took her own life. I was the only person who knew who had done it. And I was the one who helped cover for him. When Lily's mother knelt at my feet, begging me to tell the truth, I turned away with a cold face. When the people in town called me heartless and smashed my door, I let my dog, Buddy, attack them without hesitation. Ten years later, I was dying. My long-lost best friend, Claire Sutton, returned as the wealthiest woman in the country. The first thing she did was drag me onto the memory-trial platform normally reserved for death-row prisoners. "Rachel Vale, you disgusting animal. You protected a rapist. Lily and I were blind to ever call you our friend! "Lily has been dead for ten years, and you let her attacker walk free for ten years! "Today, I'm going to use the memory extractor I developed to see exactly who you've been protecting!" But when the real culprit appeared before everyone, Claire Sutton collapsed on the spot. She could barely stay on her knees.

Mom is very biased. Every night, she will pour me a glass of milk before bedtime, simply because my grades are the best. My twin sister, Melody York, and my younger brother, Jason York, have never received this treatment before. On the night before my college entrance exam, Mom brings me a glass of milk before my bedtime as usual. But the next day, I end up collapsing in the exam venue even though I've always been healthy. Because of that, I miss out on the college entrance exam, causing me to fail. Meanwhile, Melody, whose grades have always been terrible, miraculously gets into an outstanding university. Mom consoles me, telling me that it's fine to just repeat the senior year. Every night, she prepares the same glass of milk for me as usual. Before the second college entrance exam, my cousin, Annie Wood, is staying over at my place temporarily. She wants to have a taste of my nighttime milk, only to get berated by Mom for being shameless. But halfway through the exam, I suffer from an intense stomachache all of a sudden. After that, I get sent to the hospital for emergency treatment. That year, I end up failing the exam again. But Annie, who comes from a vocational high school, gets into a pretty good university thanks to her scores. The entire family is elated, to say the least. But the fact that I have to repeat my senior year for the third time makes me the butt of everyone's jokes. I don't understand why all sorts of health problems will plague my body when it's time for my college entrance exam. When I'm taking the exam for the third time, I tell myself that this is my final chance, so I mustn't slack off no matter what. Three days before the exam, the only food I've ingested is the food offered by the school's cafeteria, just in case I run into more health problems on the day of the exam. But on the night before the exam, Mom brings me yet another glass of milk before bedtime.

My dad always calls me a lazy bum. It is because I often fall asleep without warning. I sleep in class, while eating, and even while crossing the street. My homeroom teacher, Yvonne Smith, suggests that he take me to a hospital for an examination. But Dad scoffs and says, "He's just staying up all night playing on his phone." After that, he confiscates my phone and removes the lock from my bedroom door. Every time I get sleepy, he slaps me. I don't want to be hit, and I don't want to make Dad angry. So, I start pinching my thighs, pulling out my hair, and even rubbing hand sanitizer spray under my nose to stay awake. But whenever the overwhelming drowsiness hits, nothing can stop it. On the day of the final exams, Dad happens to be one of the invigilators. I bite my lip until it bleeds and silently beg myself inwardly, "Just this once, please stay awake." Still, I fail to fight off the sleepiness. Suddenly, someone flips over my desk. The chair tips with it, and I crash to the floor. My temple slams into the corner of the desk, and darkness instantly floods my vision. Dad stands over me, furious and disappointed. "Zach Davies, are you really so obsessed with sleeping that you don't even care about your final exams? If you're that lazy, then stay down there and keep sleeping!" I lie sprawled across my exam paper as my vision slowly fades away. Dad, I think I am going to sleep for a very long time…

My husband, Fabian Hunt, is a neurologist. To spend the rest of his life with his colleague, Yelena Walker, he's been working day and night in the lab for the last three months. Finally, he succeeds in developing an experimental drug that can erase memories. I happen to see his tablet one day. He forgets to log out of his account, so I go through his chat history. Yelena: "Fabe, when can we finally be together without hiding?" Fabian: "Darling, just wait a little longer. Once I switch Anya's vitamin pills for the experimental drug, she'll lose her memory. After that, she'll ask for a divorce herself, and I won't have to take any blame." In an instant, I feel a chill run down my spine. So, he's willing to erase my memories of our time together just to get me to leave him. Since that's the case, I'll give the adulterous pair what they want. But when I start to forget one anniversary after another, Fabian asks me in a panic, "Anya, how can you forget everything about me?"

Mom always said I was dead to the world when I slept. I would suddenly doze off in the middle of class, while eating, even halfway across the street. My homeroom teacher suggested I get checked at a hospital, but Mom brushed it off with a scoff. "She just stayed up all night on her phone!" After that, my phone was confiscated, the lock on my door was removed, and every time I showed the slightest sign of drowsiness, I got slapped awake. I did not want to be hit, and I did not want Mom to get angry, so I started pinching my thighs, yanking my hair, even downing medicated oil just to stay awake. But when that wave of sleep hit, nothing could stop it. On the day of the final exam, Mom happened to be assigned as one of the proctors. I bit through my lip, silently begging myself, 'Just this once. Just hold on.' But in the end, I still couldn't fight it. The desk was suddenly flipped over. I went down with my chair, crashing hard onto the floor. My head struck the edge of the desk, and darkness swallowed everything in an instant. Mom stood beside me, furious and disappointed. "Cecelia Thorne, are you really so obsessed with sleeping that you don't even care about your final exams? If you're that lazy, then lie there and keep sleeping!" I lay sprawled over my exam paper, my vision dimming bit by bit. Mom, this time, I might really sleep for a long, long time.
