Why Do People Dream?
人为什么会做梦
精读先不看文字，完整听一遍。
-
Dreams occur mainly during REM sleep, a stage when brain activity resembles wakefulness but the body stays paralyzed.梦境主要发生在快速眼动（REM）睡眠阶段，此时大脑活动类似清醒状态，但身体处于麻痹状态。
-
Scientists think dreaming helps sort memories, strengthen learning, and process emotions from the day.科学家认为，做梦有助于整理记忆、巩固学习效果，并处理白天的情绪。
-
During REM, the brain reactivates neural pathways used while awake, linking new experiences to older knowledge.在REM阶段，大脑会重新激活清醒时使用的神经通路，将新经历与旧知识联系起来。
-
People who learn a skill and then sleep well remember it better than those who stay awake all night.掌握一项技能后睡个好觉的人，比整晚不睡的人记得更牢。
-
Strong emotions—especially fear or stress—often show up in dreams because the amygdala stays highly active then.强烈情绪——尤其是恐惧或压力——常出现在梦中，因为此时杏仁核仍高度活跃。
-
Not everyone recalls dreams, but nearly everyone has them unless brain injury or certain medications interfere.并非所有人都能记住梦境，但几乎人人都会做梦，除非脑损伤或某些药物干扰。
-
Lucid dreaming happens when a person realizes they’re dreaming and can sometimes guide the story consciously.清醒梦指人在梦中意识到自己正在做梦，有时还能有意识地引导梦境情节。
-
Nightmares may help prepare us for real threats by safely rehearsing danger responses in the sleeping brain.噩梦可能通过在睡眠中安全演练危险应对方式，帮助我们为真实威胁做准备。
-
Dream content changes with age: children dream more about animals and family, while adults dream more about work and social life.梦境内容随年龄变化：儿童多梦见动物和家人，而成年人则更多梦见工作与社交生活。
-
Though dreams feel vivid and real, they usually last only 5–20 minutes and fade quickly upon waking.尽管梦境感觉生动真实，但通常只持续5至20分钟，醒来后很快消退。
