报告显示，学生更有可能出现睡眠瘫痪，比例高达28.3%。

Some people report the feeling that someone or something is trying to strangle or choke them or will see someone coming into their room and not able to move or scream, experts say. It can also happen when the person is awake, lasting from a few seconds to a minute or two. It's associated with hypnagogic hallucinations, which occur as a person is falling asleep.

专家称，有些人报告说，睡眠瘫痪的感觉就像有人或者有东西在试图把他们勒死或掐死，又或者是看到有人进到了房间里，但他们却无法移动或者叫喊。睡眠瘫痪也有可能发生在人醒着的时候，过程会持续几秒到一两分钟。它与催眠幻觉有关，通常发生在人睡着的时候。

For most people, “it is not indicative of any kind of disease,” said Watson. While the experience feels frightening, the episodes last only a few seconds or minutes at most.

沃森博士说，对于大部分人来说，“睡眠瘫痪并不意味着任何疾病”。尽管这种经历很恐怖，但是它每次只会持续几秒，最多几分钟。

Most people slip out of it as quickly as they fell into it. A light touch from a partner can be enough to stop it, he said.

他说，大部分人一进入睡眠瘫痪就能够抽身而出。伴侣的轻轻触碰就可以阻止睡眠瘫痪的持续。
