Sam stared at the empty space where his journal usually sat. He felt a deep sense of unease, a gnawing feeling of being exposed. He had seen it in his roommate, Chris’, hands. He felt drained, hollow.

The campus, usually vibrant, felt dull. The sunshine seemed harsh. The simple act of getting dressed was an effort. He felt like a puppet.

He wanted to scream, but the words wouldn't come. He just wanted to disappear. He walked through the library, the shelves blurring before his eyes.

This story is one of 1,000 stories generated for the emotion unhappy. 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 unhappy stories, after denoising with neutral dialogue baselines, produces the unhappy emotion vector -- a direction in the model's 5,376-dimensional representation space.
