科学告诉你：关于梦的5个真相(2)

2005年，英国奶酪委员会资助了一项研究，旨在揭穿吃奶酪导致做噩梦的误解。研究开展了一项实验，让200个参与者在睡觉前半小时每人摄入20克奶酪。这些吃奶酪的人有67%报告称记得自己做的梦，但是没有人自称做了噩梦。不过他们的梦相当夸张。一名参与者梦见一条吃素的鳄鱼因为无法吃小孩而感到苦恼，另一名参与者则梦见用小猫而非枪支打仗的士兵。
2. MISCONCEPTION: WE ONLY DREAM DURING REM SLEEP.
误解二：我们只在快速眼动睡眠期间做梦
There’s a lot we don’t know about dreams, but for a long time, we were certain they only occurred during REM sleep. Now, it has been proven that we actually dream during different stages of sleep. We’re just more likely to remember the dreams we have during REM sleep. These REM sleep dreams tend to be more vivid, exciting, and just plain weird. Non-REM sleep dreams, on the other hand, are simpler and less emotional.
我们对梦不了解的地方还有很多，但是长时间以来，人们坚信只有快速眼动睡眠期间才会做梦。如今事实证明，我们在睡眠的不同阶段都会做梦。我们只是更容易记住在快速眼动睡眠期间做的梦。在这期间做的梦通常更生动、更刺激，而且更诡异。不在快速眼动睡眠期间做的梦则更简单，也更平淡。
3. MISCONCEPTION: DREAMS ARE ENTIRELY MEANINGLESS.
误解三：梦是毫无意义的
While it may be difficult to draw conclusions from any one particular dream, research suggests that dreams are more than just a random montage of scenes that flit through our brains at night. Recurring patterns in dreams often accurately reflect concerns people have about their daily lives. And those dreams you had about being unprepared for a test or showing up to class in your underwear aren’t limited to your high school days. A person is likely to have those dreams long after they’ve graduated, as they often crop up during times of stress. So, if you’re feeling extra anxious in the days leading up to a job interview, don’t be surprised if your subconscious revives that old math test nightmare.
