A Sudden Point

W-Wait! What just happened?! One second I was totally frozen stiff, and the next—GAAAH! My right arm literally jerked upward on its own! Look, my index finger is completely sticking straight up at the sky! Did the wind do this?! No, wait, I can actually wiggle it! I leaned straight toward the chair's backrest and gave the wood a sharp tap. It made a real sound! I'm moving! I'm genuinely moving right now!
