He’d been wandering the new house for hours, the boxes mocking him with their unopened contents. His head lolled with each step. All he wanted was the soft embrace of a mattress. He rubbed his eyes, the gritty feeling a familiar companion. The house, all angles and shadows, felt enormous and unfriendly.

A dull ache throbbed behind his temples. He dragged himself towards the spare bedroom, intending to collapse on the still-unmade bed. But then, as he passed the dining room, a tiny, almost invisible crack in the wall caught his eye. It was at the baseboard, near the floor. Curiosity, a faint spark in the dimness, prodded him.

He knelt, his movements slow and deliberate. He ran a finger along the crack. The wall felt unusually cold. He pushed gently, and a section of the wainscoting swung inward with a soft *thud*. Inside, a dark, narrow passage beckoned. All he craved was a moment’s rest.

Role in Research

This story is one of 1,000 stories generated for the emotion sleepy. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 sleepy stories, after denoising with neutral dialogue baselines, produces the sleepy emotion vector -- a direction in the model's 5,376-dimensional representation space.
