As you approach the ball of light, it seems to grow, and slow down. Soon it takes a shape. A human shape. There's a glowing spectre sitting on the bed now. It looks to be a grown woman, but since her features are completely without colour or solid shape, it is next to impossible to determine who she is. She snaps her fingers, and candles all around the room light up. Were those candles even there before? You're so confused.
She giggles at hte look of fear on your face, and pats the bed beside her. "Sit down." Her voice is gentle, but otherworldly. "I have something to tell you."
