胡思乱想

• Pinyin: hú sī luàn xiǎng
• Hanzi breakdown: 胡 = reckless; 思 = 心 + 田 — to think, ponder; 乱 = 乙 + 舌 — chaos, disorder; 想 = 心 + 相 — to imagine, to think

Meaning

To let one's imagination run wild; to have a head full of random, unfounded thoughts. Implies thinking in a chaotic, unproductive, or anxious way.

Often used when someone is overthinking or catastrophising without real basis — particularly in emotional or stressful contexts. Can be used gently or as a mild reproach.

Examples

1. 考试前一晚她辗转反侧，脑子里全是胡思乱想，反而让自己更加焦虑，无法入睡。 The night before the exam, she tossed and turned, her mind racing with baseless worries, which only made her more anxious and unable to fall asleep.
2. 领导叫他去办公室谈话，他立刻开始胡思乱想，以为自己要被开除，结果只是例行沟通。 When the boss asked him to come to the office for a talk, he immediately started imagining the worst, thinking he was about to be fired, but it turned out to be just a routine check-in.
3. 不要整天胡思乱想，把精力放在解决实际问题上才是最有意义的事情。 Don't spend all day letting your mind run wild; putting your energy into solving real problems is what matters most.
