A man named Bai recorded his friend fainting momentarily on a roller coaster ride in southern China.

The video was filmed in the city of Zhuzhou in Hunan Province on April 12.

The person involved, Mr Weng, admitted to having a fear of heights but decided to confront it by trying the roller coaster.

As they reached the final tunnel, everything went dark, causing his heart to race and his perception of the outside world to become blurry.

After the ride came to a stop for about seven or eight seconds, he regained consciousness.

The video was provided by Mr Bai.

4月12日，湖南株洲。白先生在玩过山车项目时，记录下自己的恐高朋友被吓晕，短暂性吓晕失忆的画面。当事人翁先生称，自己有一些恐高症，当时也想着去尝试克服下，在过最后一个山洞时，因为里面太黑暗什么东西都看不见了，心跳加速就像虚脱了一样，对外面的感知就模糊了，最后车停下来大概七、八秒，自己才清醒了过来，也算是一次成功的挑战。视频由白先生提供。
