John sat at the computer, attempting to work. The screen swam before his eyes. He had been struggling to stay awake for the past hour and now, every word blurred. He had been planning to finish his proposal, but the effort required felt Sisyphean. He leaned his head on his desk, the cool surface offering a moment of relief from the internal furnace of fatigue.

A knock, a delivery man, handed him a letter from the police. It stated the house's past, the unfortunate event, the investigation. John felt a dull sense of detachment as he read, a hollow feeling. His brain felt like a thick, foggy field. He only wanted the comfort of stillness, an end to the mental strain, and the quietude only sleep could offer.

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.
