Sleep paralysis isn’t a medical emergency. Being familiar with the symptoms can provide peace of mind.
The most common characteristic of an episode of sleep paralysis is the inability to move or speak. An episode may last for a few seconds to about 2 minutes.
You may also experience:
- feeling as if something is pushing you down
- feeling like someone or something is in the room
- feeling fear
- hypnagogic and hypnopompic experiences (HHEs), which are described as hallucinations during, right before, or after sleep
