It's completely normal for a person who experiences sleep paralysis to feel this way. I've had lucid dreams and sleep paralysis since I was a kid, and lemme tell ya, I know how terrifying it can be. I thought a demon was trying to kill me, and believed for years that I'd been abducted by aliens. If this happens to you, when you lay down, consciously set the intention that nothing can touch you; anything negative around you is banished and you're protected by *insert whatever you believe in* Angels, God, Jesus, guides, etc. You might even smudge your house with sage. It's the belief and intention behind the action that counts. We have more control/power over our minds than we think.
