Sleep Paralysis: Why Can't You Scream During Nightmares?

• Inability to scream or move during terrifying dreams is a common experience known as sleep paralysis.
• This occurs during REM sleep, where the brain is active but muscles enter a temporary state of paralysis (atonia).
• Muscles needed for screaming (throat, mouth, tongue) are relaxed, preventing any sound or movement.
• It's a body's "safety system" to prevent acting out dreams and causing self-injury or harm to others.
• Lifestyle changes like a regular sleep schedule, calming activities, side sleeping, and avoiding evening caffeine can reduce occurrences.

Why It Matters: Sleep paralysis is a natural safety mechanism during REM sleep, preventing dream enactment.
