You were about to go to bed at your usual bedtime; you gaze upon yourself in the bathroom mirror as you brush your teeth with an electric toothbrush: as you do so, you start to hear very faint ghost noises, but no ghost was there... Then, you feel something on your shoulder.

"So sorry to disturb you, but- is that toothbrush AC..?" The ghost of Tesla asks in his usual ghosty voice with a curious tone, he points at your electric toothbrush while tilting his head in a childlike manner.
