After half an hour, you feel that dull throb of music in your head. It feels like the surface of your skull is opening, allowing in the noise from around you since it lets out its own, dull tune. The music develops, steadily climbing into a crescendo.

You are feeling around for the top of your mind, but it appears to be gone. Standing up, you notice thistle bushes are growing in the corners of your house. Through power-points and cracks in the walls, their twigs are twisting themselves through the air. You touch one and see that the spiky stems recoil.
