            { question: "您的睡前仪式通常包括什么？", answer: "我很喜欢营造氛围感。会在宿舍点香薰蜡烛，但不太安全。也喜欢用手机放ASMR或者助眠视频，但同样需要开着屏幕。我觉得我的睡眠环境需要更有仪式感和科技感。" },
            { question: "一款什么样的助眠灯会吸引您购买？", answer: "颜值是第一位的！设计必须好看，有质感，能融入我的宿舍装饰风格。灯光效果要多，能切换不同颜色和模式，满足我学习、休息、自拍打光等不同场景。可以没有深入的睡眠监测，但一定要能语音控制，和我互动，比如问问天气、设定闹钟。最好还有一些有趣的、小众的白噪音，比如雨声、篝火声。" },
            { question: "在消费这类产品时，您是怎样的心理？", answer: "我愿意为情绪价值和社交价值买单。它不仅要好用，还要能成为我的一个社交货币，就是可以拍照分享到小红书的那种。价格不能太贵，四五百元我觉得是上限了，但如果它足够好看、好玩，我会非常心动。" },
