"There's this sudden crescendo of noise, then a profound and jarring explosion of sound, electrical fizzing and a bright flash in my vision, like someone has lit a spotlight in front of my face."

“噪音突然增大，然后我听到巨大、刺耳的爆炸声，看到电火花和明亮的闪光，就像别人把聚光灯打到我的脸上一样。”

That's how Niels Nielsen describes what it's like to live with "exploding head syndrome" - an unpleasant and sometimes terrifying sensation. Others describe it as like a bomb going off next to their head as they fall asleep. Sometimes it occurs just once in a lifetime, for others it happens multiple times a night.

这就是尼尔斯·尼尔森对“爆炸头综合症”的描述——一种让人不适，有时甚至让人感到恐怖的体验。也有其他人将这种症状描述为，就像是快睡着时头附近有炸弹爆炸一般。有些人一生只经历一次，另一些人则一晚会经历多次。

The physician Silas Weir Mitchell first described the disorder in 1876, when he described two men who suffered from what he called "sensory discharges" - the men themselves described it as hearing "loud bells" or a "gunshot" that would wake them from sleep.

1876年，外科医生西拉斯·魏尔·米歇尔首次记述了这种病，他当时描述称两名男子出现了他称之为“感官放电”的症状——他们自称因听到“巨大的钟声”或“枪声”而惊醒。
