Human: Write a detailed description of a foreboding scene outside of a lake with an island and shadows. Assistant: 
The packed reeds underfoot yaw and pitch with the shallow waves near the shore as they drift with the currents across the water of the lake. Jostled by adjacent hummocks, the relative position of each individual islet rarely changes, but the distance from one island to the next seems to vary from day to day. Dark shadows glide beneath the surface of the water around you, and an occasional cry of a nesting gull echoes mockingly from the shore.
