LANCE

I jumped on my feet and readied my fist. The voice, whoever it is, laughed. Alpha Beast was up and alert, squinting and darting his eyes across the room.

He heard the voice too. It wasn't my imagination. Someone is here. A ghost? No. A ghost don't talk nor laugh without spirit box. Paranormal investigators from tv channels taught me that.

"Who are you?" I demanded. The empty lunch boxes, suddenly hovered in the air and arc itself towards the nearest trashbin. The table was wiped clean. The kitchen sink's empty dishes wash itself. Ragged clothes wiped the kitchen top, the window sill. The blinds tie itself into a knot, opening the window and letting the strong wind outside rattle the glass.
