Sarah squinted at the screen, the notification still blinking on her phone. *Your results are in!* She read them again, the words somehow sharper and less real than before.

She rested her forehead against the cool, smooth surface of the steering wheel.

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.
