世界上有不少人相信鬼的存在。其实，大多数“见鬼”经历都是可以用科学来解释的。你所害怕的“鬼”，往往只是一种错觉。

1. ELECTROMAGNETIC FIELDS 电磁场

For decades, a Canadian neuroscientist named Michael Persinger studied the effects of electromagnetic fields on people's perceptions of ghosts, hypothesizing that pulsed magnetic fields, imperceptible on a conscious level, can make people feel as if there is a “presence” in the room with them by causing unusual activity patterns in the brain's temporal lobes1. Persinger studied people in his lab wearing a so-called “God Helmet,” finding that certain patterns of weak magnetic fields over someone's head for 15 to 30 minutes can create the perception that there's an invisible presence in the room.

加拿大神经学家迈克尔·波辛格花了几十年研究电磁场对于“见鬼”的影响后做出了一个假设，那就是人在意识层面察觉不到的脉冲磁场可以通过引发大脑颞叶的异常活动，让人们感觉屋里有“鬼”。波辛格在实验室里让人们戴上所谓的“上帝头盔”，并通过研究发现，人的大脑受到特定模式的弱磁场影响15到30分钟后，就会产生屋里有鬼的感觉。

2. INFRASOUND 次声波

Infrasound is sound at levels so low humans can't hear it (though other animals, like elephants, can). Low frequency vibrations
