The droning of the lecture hall barely registered with Liam. He slumped in his uncomfortable chair, the words of the professor washing over him like a distant tide. He rubbed his eyes repeatedly, fighting the urge to completely succumb to the feeling of heaviness that had settled over him. He had stayed up all night to study.

He was ushered in by the receptionist. The therapist greeted him with a voice that was both familiar and chilling. “Liam, have a seat.” It was Jessica, the girl who was always causing trouble in the school. Liam struggled to focus.

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.
