Sarah slumped onto the curb outside the stadium, her duffel bag thudding softly beside her. The late afternoon sun cast long shadows, painting the scene in hues of orange and purple. The celebratory shouts of the chosen team echoed from within, but they sounded distant and muted to her. Her eyes felt gritty, as if sandpaper had been rubbed across them. She wanted nothing more than to curl up in a ball and disappear. A yawn escaped, followed by a long, drawn-out stretch that did little to alleviate the pervasive feeling of fatigue that clung to her.

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.
