What is sleep paralysis?

ANSWER

Sleep paralysis is a feeling of being conscious, but unable to move. It happens when you pass between stages of wakefulness and sleep. During these transitions, you may be unable to move or speak for a few seconds up to a few minutes. Some people may also feel pressure or a sense of choking.
