Eliza sat slumped in the worn leather armchair, the antique lamp casting a warm glow on the sheet music scattered across the table. Her head nodded, then jerked back up, the movement a repeated, frustrating exercise. A tremor ran through her, which she tried to hide. It was cold in the room, but she didn’t want to get up and go to the fire. Her mind was a jumble of half-formed thoughts and fleeting images. The melody, her song, started on the radio, carried on the airwaves, from a station she barely ever listened to.

The singer's interpretation was… different. Not bad, just unfamiliar. She wanted to stand up, to pace, to absorb every detail. She felt a kind of heaviness in her limbs that kept her rooted to the spot. Her eyes slipped closed for a moment. She squeezed them shut and opened them again, the song still playing. She hoped the singer knew the feeling she put in it.

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.
