The lecture hall hummed with the quiet rustle of papers and the incessant clicking of keyboards. Sarah rested her head in her hands, the cool surface of the desk a small comfort against her throbbing forehead. The professor’s voice was a distant drone, a monotonous soundtrack to her internal struggle. She felt weighed down, like she was trying to wade through molasses. The urge to close her eyes was overwhelming.

Suddenly, a notification popped up on her laptop screen. "Congratulations, Sarah! Your essay is an example!" She barely registered it at first. She was too occupied with the struggle to keep her eyes open. She tried to focus, to read the email, but the words swam before her. "Oh god," she whispered, her voice barely audible. The classroom seemed to spin.

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.
