Can lucid dreams kill you？

你有沒(méi)有在做夢(mèng)的時(shí)候清楚地知道自己在做夢(mèng)，并且清楚地思考自己在夢(mèng)中的行為的經(jīng)驗(yàn)？這叫清醒夢(mèng)。清醒夢(mèng)和別的夢(mèng)不一樣嗎？

When you’re asleep and dreaming， yet become aware that you’re having a dream， that’s lucid dream. This type of dream occurs when the brain slips into a zone between deep REM sleep and wakefulness.

During a lucid dream， events can feel quite real. Let’s say， for example， you dream you’re driving a car along an undulating road. You crest a hill and start your downward trajectory， tap the brakes and realize they don’t work. You know you’re going to die， and， indeed， you do. But if you die in your dream， will you die in real life？

The answer， thank goodness， is no. At least， we think it’s no. The truth is， if someone were to die as the result of a lucid dream， we’d have no way of knowing. That person couldn’t tell us about their dream experiences， after all， because he or she would be dead.

There could be some mental benefits to losing your life in a dream， though. If you remember having a dream — even if it was a bad or scary dream — you’ll at least know why you’re feeling unsettled during your waking hours that follow. That’s better than a doomed feeling when you simply died in a dream you don’t remember.

A study of college students found that lucid dreams were seven times more likely to make nightmares more tolerable. And， if participants realized they were dreaming during a nightmare， they felt comforted about 60 percent of the time， which could go a long way when you face death in your dreams.
