Mr. Harris, the art teacher, rubbed his eyes, the morning’s sun still doing battle with the haze in his brain. The classroom, normally vibrant with color and activity, seemed muted. He was exhausted after the end-of-year art exhibition. He struggled to stay upright in his chair.

A large canvas, covered in a cloth, leaned against his desk. He pulled off the cloth slowly. It was a painting of a landscape, a gift from a former student. He looked at the painting, and felt his chest lighten.

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.
