Paralyzed in suffocating Darkness

"I was trapped in an absolute, suffocating darkness, locked completely rigid from head to toe while this terrifying sensation of total helplessness pressed down on my chest. I couldn't see my room or make out any distinct shapes around me, but every muscle in my body was completely paralyzed no matter how desperately I screamed inside my own head to move just a single finger. That horrible, heavy weight held me pinned to the spot until my eyes violently snapped open into the dim morning light. I lay there in my bed, heart pounding like a hammer against my ribs, trembling in total terror with the vivid, awful memory of being frozen still clinging to my skin."
