The fluorescent lights of the diner buzzed, a high-pitched drone that seemed to vibrate through Leo’s skull. His coffee cup was empty, a testament to his utter lack of energy. Across from him, a woman with a cascade of dark curls was laughing, her voice a tinkling bell. She was recounting a story about a surprise weekend getaway. Details of a beach, of the ocean. Leo felt a pull in his stomach, a recognition he couldn't quite place. He wanted to lean forward, to ask a question, but his limbs felt heavy. He could barely lift his fork. “And he told me I was the only girl he’d ever felt this way about…” she said, her voice dropping. Leo stared at the checkered floor.

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.
