I wake from my slumber when the clock strikes midnight, when the moon shines bright, dark made light. When you drowse, I stir, your mind a blur; your sense in a stupor, as it were. Too late, you left the door unlocked! You won’t suspect, and I won’t get caught. You think you’re in deep, but your judgment is flawed. You fight for your life, and for that I applaud. Once I grab hold, try as you might, you can’t move a muscle nor terror imply. No one can hear you, there’s no place to hide; you try to make a break, but I have your limbs all tied. Your heart is racing, you’re screaming, no sound. Are you suffocating, chest crushed, spellbound? I share whispers in kind, shivers down your spine. I question your sanity and make your thoughts run blind. The end is in sight, dear, I’m your only hope. I’ll soon set you free and leave you alone. But before I go, just so you know, I’ll leave no mark — presto! “No harm, no foul”, so it goes. Until tomorrow, I suppose. Who am I?
Answer: Sleep paralysis.
